Space Physics research inspires Art Exhibition
This week marks the opening of the Art and Light exhibition at Otago Museum. The idea of he display was to mark 2015 as the Year of Light. Dr. James Brundell and Craig Rodger worked with artists David Green and Sarah McKay to inspire three different art installations. One made use of our real-time wideband VLF feed to detect the sferics generated by lightning and project images of lightning on the viewers body. Another used whistler mode chorus recordnigs made by Craig's colleagues at the University of Iowa from their EMFISIS experiment on the Van Allen Probes. Finally, the work by Sarah McKay was inspired by the idea that the radio waves we use are a type of light, but in a range we cannot see with our eyes. A story including descriptions of our work was published in the Otago Daily Times on 17 August 2015 ("Seeing the light"). The exhibition is open from 15-30 August [19 August 2015].
Craig Rodger visits Minneapolis
Last week Prof. Craig Rodger flew out of Iowa City to undertake a collaborative visit to the Space Physics researchers at Augsburg College, Minneapolis. While in the twin cities Craig went to see colleagues at the University of Minnesota. He also gave a colloquium to staff and students from Augsburg College, with some visitors from the University of Minnesota who came across the river for the talk [10 August 2015].
Craig Rodger goes to the Van Allen Probes Science Working Group in the USA
This week Prof. Craig Rodger travelled from Iowa City to Columbia (Maryland) to attend a set of meetings at the Applied Physics Laboratory of Johns Hopkins University. This was a multi-day set of meetings around NASA's Van Allen Probes. The first day was devoted to Instrument Team Meetings, and Craig have a presentation at the EMFISIS team meeting. After this Craig was part of the wider Science Working Group workshop. He was supported by EMFISIS funds from the University of Iowa and the Fulbright New Zealand Scholar Award which is reported below [30 July 2015].
Otago Space Physics team contributes to interview on "mini ice age"
Social media apparently reacted strongly to a Royal Astronomical Society press release about the possibility of an upcoming Maunder minimum and that this could trigger a Mini-Ice Age in ~15 years. Prof. Craig Rodger was the first of five researchers interviewed on the Sunday Morning with Mark Sainsbury on RadioLive. The interview is available online here. Several weeks later it was on the "most popular" downloads for the Mark Sainsbury show! [19 July 2015]
Dunedin Space Physics Observations Reported in Physics World Magazine
This month's edition of Physics World magazine includes an article about whistlers recorded in Dunedin that were produced by Alaskan volcanic eruption-triggered lightning. There has been quite a lot of interest in volcanic lightning in the last few years, and World Wide Lightning Location Network (WWLLN) observations are now being used to provide early warnings of eruptions (one of the WWLLN central processing computers is hosted at Otago, and we operate 3 WWLLN receivers around the world). South African MSc student Claire Antel (University of Cape Town) used whistler observations from Dunedin, collected by the Eötvös University Automatic Whistler Detector (AWD) we host, and combined them with WWLLN lightning to show some of the Dunedin-reported whistlers were being generated from the volcanic lightning! The research was originally published as a paper in Geophysical Research Letters (doi:10.1002/2014GL060332, 2014), and has now been described in this Physics World magazine article (requires subscription) and the associated press release. The article is called "Whistling volcanoes", but the prize clearly goes to the title of the press release: "Flashes in the ashes: How volcanic lightning is helping to demystify the Earth’s plasmasphere" [3 July 2015].
Otago Space Physics "Hits the Road"
This week the entire Space Physics group is travelling for work, but mostly not together! Prof. Craig Rodger left the University of Iowa (USA) where he is reseacrhing supported by a Fulbright New Zealand Scholar Award and travelled to Prague (Czech Republic) to represent New Zealand at the 26th IUGG General Assembly. Assoc. Prof. Neil Thomson is in Canada and Denmark to undertake a set of field campaign measurements. PhD student Aaron Hendry, who was working British Antarctic Survey (UK), finished his European holiday and arrived in Prague to join Craig at the IUGG conference. PhD student Kathy Cresswell-Moorcock left Dunedin for Boulder (USA) to take part in the NCAR Advanced Study Program Summer colloquium entitled Climate, space climate, and couplings between. And this week Dr. James Brundell and PhD student Emma Douma went to Christchurch (New Zealand) to attend the 2015 Antarctic Science Conference. It must feel very quiet in the Space Physics lab space [1 July 2015].
Craig Rodger's Fulbright Scholar Award taken up in the USA
Prof. Craig Rodger was awarded a Fulbright New Zealand Scholar Award to spend time working and living in the USA. He left New Zealand last week (28 May), and is now in Iowa City. The Fulbright Scholar 5-month period is split between the University of Iowa in Iowa City and the University of Colorado in Boulder. Craig will spent about 6-months in the USA on sabbatical, so after the Fulbright period he will also travel to Hanover to visit Dartmouth College supported by a Matariki Network of Universities' (MTU) Travel Award [5 June 2015].
Aaron working at the British Antarctic Survey (Cambridge, UK)
Space Physics PhD student Aaron Hendry left New Zealand on Friday 22 May 2015 to undertake a collaborative visit to the British Antarctic Survey. He is working with our long-term collaborator Dr. Mark Clilverd to better understand EMIC-driven electron precipitation into the atmosphere, combining satellite and ground based data. Both magnetometer and AARDDVARK data are being used. Aaron is supported by a Claude McCarthy Fellowship. He will also take a holiday while in Europe, and attend the 26th IUGG General Assembly in Prague [5 June 2015].
Emma re-joins us to undertake a PhD
Emma Douma will be pursuing a PhD in the Space physics group, attempting to understand strong diffusion. She has been awarded the prestigious Fanny Evans Postgraduate Scholarship for Women and started working towards her PhD on the 1st of March. Emma didn't really leave the group, as she undertook her Honours project research with us in 2014, and was then a summer fellowship research student [25 March 2015].
Kathy wins University of Otago PhD Scholarship
Space Physics MSc student Kathy Cresswell-Moorcock has recently won a University of Otago Doctoral Scholarship to cover three years of study for her PhD. She is staying with the Otago Space Physics group for this study which started in December 2014. Kathy also graduated with her Masters of Science awarded with Distinction on 13 December 2014 [25 March 2015].
Craig Rodger wins Editors' Citation for Excellence in Refereeing - Journal of Geophysical Research Space Physics
Prof. Craig Rodger heard today that he been recommended by the editors of Journal of Geophysical Research: Space Physics to receive the 2014 Editors' Citation for Excellence in Refereeing. JGR - Space Physics is published by the American Geophysical Union. The citation reads "One of the most important services performed for AGU is the conscientious reviewing of submitted papers. Because of the nature of the reviewing process, this service is also one of the least recognized. The purpose of this citation is to express publicly the gratitude of AGU to those whose reviews have been particularly commendable." A photo and formal annoucement is to be published in a future issue of AGU's Eos Earth & Space Science News [13 March 2015].
Craig Rodger gives plenary lecture in Svalbard
On the last day of February Prof. Craig Rodger travelled to Norway to take part in the 5th Birkeland Centre for Space Science meeting at the University Centre in Svalbard (UNIS), Longyearbyen, Svalbard. Svalbard is a Norwegian archipelago in the Arctic Ocean located about 2000km north of Oslo. Craig gave the plenary lecture at the 5th BCSS workshop on Tuesday 3 March 2015 at UNIS which was carried on the twitter feed of the Birkeland Centre. Craig combined his visit to Norway with travels to the British Geological Survey in Edinburgh and Physics at Lancaster University [3 March 2015].

Mark Clilverd visiting for his yearly time in Dunedin
Each year Mark Clilverd from the British Antarctic Survey comes to visit the Otago Space Physics group - this very long-standing collaboration has produced a lot of science, and influenced a lot of student projects. In 2015 Mark came to us for two weeks in early-mid January - at the height of a truly wonderful Dunedin summer. We celebrated his birthday with penguin spotting at the Kaitiki Point Penguin colony and have enjoyed working on our laptops in Craig's garden. Mark has also worked strongly alongside the groups 3 PhD students (Aaron, Kathy and Emma). Its been a highly productive visit with two papers finished off and another one started. We are sorry to see Mark leave, but he now heads away to Switzerland to attend a meeting at the International Space Science Institute. [23 January 2015].
Expedition 7 home from Antarctica
The seventh Antarctic expedition from the Otago Space Physics group returned to Dunedin on Thursday after a very productive week on the ice Prof. Craig Rodger and Dr. James Brundell left on the scheduled day, and returned to Christchurch only ~5 hours later than planned. They spent almost exactly one week in Antarctica, in an intensive mission to repair the AARDDVARK antenna located near Scott Base. This year the weather was kind, giving them a lot of good quality working time [20 November 2014].
Electron Precipitation Drives Ozone Losses
Energetic electron precipitation (EEP) from the Earth’s outer radiation belt continuously affects the chemical composition of the polar mesosphere. EEP can contribute to catalytic ozone loss in the mesosphere through ionization and enhanced production of odd hydrogen. However, the long-term mesospheric ozone variability caused by EEP has not been quantified or confirmed to date. We recently showed in Nature Communications, using observations from three different satellite instruments, that EEP events strongly affect ozone at 60–80 km, leading to extremely large (up to 90%) short-term ozone depletion. This impact is comparable to that of large, but much less frequent, solar proton events. On solar cycle timescales, we find that EEP causes ozone variations of up to 34% at 70–80 km. With such a magnitude, it is reasonable to suspect that EEP could be an important part of solar influence on the atmosphere and climate system.
The Nature Communications article was the result of a collaboration between the Finnish Meteorological Institute, University of Otago and British Antarctic Survey. The article produced press releases from FMI and Otago University, and lead to a number of articles in news papers, including the Otago Daily Times and the New Zealand Herland. Craig was interviewed on National Radio, which can be listened to online [17 October 2014].
Expedition 7 planning maintenance trip to Antarctica
The seventh Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Prof Craig Rodger is the event manager for Expedition 7, while Dr James Brundell is the event leader (these are the names used by Antarctica New Zealand for the roles we fill). The main goal of our travel is to repair long-term damage to our antenna, which was been in place since December 2008 but has slowly suffered in the high winds at Arrival Heights. The team is currently scheduled to travel to Scott Base on Wednesday 12 November 2017 for a 7-day highly intensive working period. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
James and Craig are heading to Scott Base to work on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. They also comprised the Expedition One team who deployed this radio receiver in December 2008; this is James' 6th visit to Antarctica and Craig's third. Expedition Seven will also gather high resolution data, undertake calibrations and make VLF radio noise observations. While planning is well underway, both Craig and James have a few other tasks to complete first – Craig leaves to China this Friday and then will travel to Finnish Lapland, while James is currently in Brazil having attended the V Brazilian Symposium on Space Geophysics and Aeronomy & IV Forum for Research and Innovation. Interested? You can read more at this webpage [9 October 2014].

Today we learnt that Space Physics PhD student Aaron Hendry has been awarded a Claude McCarthy Fellowship for 2015. He will use this funding to attend the 26th IUGG General Assembly in Prague and undertake a collaborative visit to the British Antarctic Survey. While at BAS Aaron will work with our long-term collaborator Dr. Mark Clilverd on analysis of AARDDVARK data, finishing off his research into EMIC-driven electron precipitation into the atmosphere. Well done Aaron! [2 October 2014]
Craig Rodger's Inaugural Professorial Lecture now online
Late last year Craig Rodger learnt he was promoted to full Professor, formally starting in February 2014. In early March he gave his Inaugural Professorial Lecture to a "full house" of colleagues, students, friends, family and the public. After much delay the video of this lecture has finally go online. He tries to give an overview of his research, and why it matters in the "big picture". You can see the video from the Otago Science Division Podcasts webpage, and it is also to go up at Otago University on iTunesU. Craig really pushed himself hard to make sure it was an active show, and hopes you enjoy the video. [16 September 2014]
Aaron and Craig travel to Beijing
Back in June we learnt that Space Physics PhD student Aaron Hendry had been selected to receive an URSI Young Scientist Award to attend the XXXI URSI General Assembly and Scientific Symposium at the Beijing Convention Center (BCC) in Beijing, China. In mid-August Aaron and Craig Rodger travelled to China to attend this conference. Craig went too as he was co-organising two sessions, had a separate invited talk, a couple of oral presentations and a couple of posters, plus was the official New Zealand delegate. Craig and Aaron took the day off and had a tour of Tiananmen Square in central Beijing, plus travelled out to see the Mutianyu section of the Great Wall of China. [25 August 2014]
Alex and Ian Visit Waihola School
Ian Whittaker and Alex Schwertheim visited Waihola District School and undertook Space Physics outreach activities to the primary school class there. The students, aged between 4 and 11, at this rural school were participants in demonstrations on how big and cold our solar system is. Ian and Alex showed practical demonstrations of how the Sun warms the Earth, how the Moon affects tides on the Earth and the phases of the Moon. The students then were part of a human solar system and saw a demonstration on why astronaut spacesuits are necessary. Ian and Alex were also requested to judge a cake making competition from the students - an activity they were happy to perform! This visit has appeared on the Blog page for Waihola School Room 2, including the students impressions of the activities. [22 August 2014]

Well done Aaron! [4 June 2014].
James and Craig going back to Canada
This Friday Dr James Brundell and Prof. Craig J. Rodger will be heading to Canada to visit some of the AARDDVARK receiver sites. We will go to St John's initially, to the AARDDVARK receiver there which is on the site of the St. John's Magnetic Observatory. After a couple of days working there we will travel to Ottawa (visiting Natural Resources Canada Space Weather Forecast Centre), then Edmonton (Space Physics Group at the University of Alberta). At this point we split up. Craig will head to Calgary (visiting the University of Calgary), while James will leave Canada and go to Seattle (visiting the University of Washington's Department of Earth and Space Sciences). As part of this trip we will be returning to the Ministik Lake AARDDVARK antenna which has certainly had a very hard life. Since our last visit in July 2013 (see the news bulletin below) the data quality has been pretty good, but it has continued to be a somewhat mid-behaved [15 May 2014].
Space Physics Material launched on the Science Learning Hub
Craig was filmed back in late March 2013 by a team from the New Zealand Science Learning Hub, who were putting together a new resource called "Gases and Plasmas". The Science Learning Hub provides resources for teachers of school years 2-10 and is funded by the Ministry of Business, Innovation and Employment. The Gases and Plasmas context includes multiple content from the Space Physics group, including radiation belt and space weather research, Red Sprites, our WWLLN lightning research, and overviews on plasmas and studying Physics. And more, actually [29 April 2014].
Ian and Aaron off on seperate overseas trips
Last Friday (25 April 2014) Space Physics group PostDoc Dr Ian Whittaker left from Auckland airport to attend the European Geosciences Union General Assembly 2014 in Vienna (17 April -2 May). Ian will be travelling in Europe after the meeting, including in Switzerland and the UK. The next day Space Physics PhD student Aaron Hendry left from Auckland airport to attend the Japan Geoscience Union Meeting 2014 in Yokohama (28 April - 2 May), after which he will travel in Japan. Both are giving oral presentations at these major conferences. Busy times for the group! [27 April 2014].
Mark Clilverd joins us for more than 3 months
Each year Mark Clilverd from the British Antarctic Survey comes to visit the Otago Space Physics group - this very long-standing collaboration has produced a lot of science, and influenced a lot of student projects. This year Mark came to Dunedin for more than 3 months, having a sabbatical" in our group. All of the Space Physics group, staff and students, worked alongside Mark in this time period - a bunch of our scientific questions have been clarified. But now Mark is heading homewards, leaving us on Monday next week [7 April 2014].
SCOSTEP launches the VarSITI programme
Scientific Committee on Solar Terrestrial Physics (SCOSTEP) launched its new scientific program VarSITI (Variability of the Sun and Its Terrestrial Impact) on Monday 13 January 2014. VarSITI is an international interdisciplinary research program that will run for next five years. The VarSITI program is established after a collective effort by the international scientific community over the past year. It will focus on four major themes: solar magnetism and extreme events, Earth impacting solar transients, magnetospheric changes, and consequences and processes in Earth's atmosphere. In order to make progress on these themes, four scientific projects have been defined, which are headed by international experts.
One of the 4 projects inside the VarSITI programme is SPeCIMEN (Specification and Prediction of the Coupled Inner-Magnetospheric Environment), which is lead by Otago academic Assoc. Prof. Craig J. Rodger and UCLA-researcher Dr. Jacob Bortnik. More details at the VarSITI website, the SCOSTEP website, or from this YouTube movie associated with the VarSITI programme launch [13 January 2014].
Craig Rodger promoted to Professor!
Late in 2013 the University of Otago annouced that two Physics Department staff were being promoted to Professor, included Craig Rodger. The full details on their promotions and the other Otago staff joining them in their new role can be found in the University Media Release [23 December 2013].
Expedition 6 home from Antarctica
The sixth Antarctic expedition from the Otago Space Physics group returned to Dunedin on Sunday after a cold time. While Dr. James Brundell and Space Physics PhD student Aaron Hendry. While theywere expected to come back to New Zealand on the Wednesday before, a series of weather-related delays kept them on the ice for several extra days. Nonetheless, they made it home, safe and well. Craig received a text message confirming this as he, Kathy and Jason were taking the train away from Najoya airport, Japan (see previous item) [17 November 2013].
Jason, Kathy, and Craig off to Japan
Tomorrow a group of us leave Dunedin, heading for the International CAWSES-II Symposium in Nagoya, Japan. Space Physics MSc students Kathy Cresswell-Moorcock and Jason Neal along with Assoc. Prof. Craig Rodger have multiple presentations to give over the 5-day meeting. Jason and Kathy have not been out of New Zealand before, so this is a very exciting opportunity [14 November 2013].
Expedition 6 wind-blown in Antarctica
The sixth Antarctic expedition from the Otago Space Physics group are currently working in and around Scott Base. This year our team has gone south earlier than normal, at the request of Antarctica New Zealand. This has produced some new challenges for the team, with colder temperatures and higher winds up around the New Zealand lab at Arrival Heights where our experiment is located. The picture below shows Space Physics PhD student Aaron Hendry beside our experiments antenna during an inspection of the equipment undertaken today. Dr James Brundell, the event leader, and Aaron have achieved quite a few of the primary goals, and will likely be returning to New Zealand this Thursday, just one day later than originally planned [11 November 2013]
Expedition 6 prepares to depart for Antarctica
The sixth Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Dr James Brundell, the event leader, has been preparing with Space Physics PhD student Aaron Hendry. They will be testing new monitoring equipment as we investigate the possibility of new recording sites around Ross Island. The team is scheduled to travel to Scott Base on Monday 4 November 2013 for a ten-day intensive working period. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
James and Aaron are heading to Scott Base to work on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. James was one of the two man Space Physics team who deployed this radio receiver in December 2008, and has returned multiple times since. The main aim for Expedition 6 is check the VLF radio noise for sites near Scott Base, in case we need to move from our existing recording site near New Zealand lab at Arrival Heights. James and Aaron will also gather high resolution data and undertake calibrations and physical maintenance of the experiment. Interested? You can read more at this webpage [29 October 2013].
James and Craig heading for North America
This Friday Dr James Brundell and Assoc. Prof. Craig J. Rodger will be heading to Canada and Seattle to visit some of the AARDDVARK receiver sites. We will go to Ottawa initially (visiting Natural Resources Canada Space Weather Forecast Centre), then Edmonton (Space Physics Group at the University of Alberta) and finally fly south to Seattle (visiting the University of Washington's Department of Earth and Space Sciences). As part of this trip we will be returning to the Ministik Lake AARDDVARK antenna which has certainly had a very hardlife. Since November it has mostly behaved, and we hope to find it in good conition [24 July 2013].
Our SPeCIMEN plan for SCOSTEP accepted!
Scientific Committee on Solar Terrestrial Physics (SCOSTEP) is an interdisciplinary body of the International Council for Science (ICSU). SCOSTEP runs international interdisciplinary scientific programs and promotes solar-terrestrial physics research. We recently helped prepare a white paper to submit to SCOSTEP, suggesting a project for their 2014-2018 Science Programme. Our project was named SPeCIMEN: Specification and Prediction of the Coupled Inner Magnetospheric Environment.
After a panel meeting in Bern, Switzerland, SCOSTEP selected our project to be one of the 3 core SCOSTEP programmes which will run in that 5-year period. Assoc. Prof. Craig J. Rodger is part of the Executive Committee which will oversee this project. He also supported the preperation of another white paper which was combined with others to produce another project for SCOSTEP's plan, ROSMIC: Role of the Sun and the Middle Atmosphere/Thermosphere/Ionosphere in Climate.
We are thrilled to hear SCOSTEP recognises the importance of our scientfic directions, and the new collaborations this will spark [14 May 2013].

[14 December 2012].
Otago Space Physics Antarctic Expedition 5 Now Home
The two-man team making up the fifth Antarctic expedition from the Otago Space Physics group to Antarctica returned to Dunedin on Tuesday this week. Dr James Brundell, the event leader, and Dr Ian Whittaker, flew out of Antarctica on the morning of Monday 3 December on a USAF C-130, and landing in Christchurch in the early evening. During thier time in Antarctica they moved our computer and electronics into a new room in the Arrival Heights Kiwi Lab, gathered data, checked the gear was well, and undertook electromagnetic noise measurements. All the data from our AARDDVARK experiment looks good, before and after the shift. Another successful (and quick) trip to Antarctica. The logistics support for Expedition 5 is provided through Antarctica New Zealand Event K060. [7 December 2012].

Update from Otago Space Physics Antarctic Expedition 5
The two-man team making up the fifth Antarctic expedition from the Otago Space Physics group to Antarctica travelled to Christchurch on Sunday to be issued their Antarctic clothing. On Monday morning Dr James Brundell, the event leader, sent us a SMS alerting us they were delayed about 1 hour, but by 706am that morning he SMSed "On plane!" and by Monday afternoon James and Dr Ian Whittaker were emailing us back in Dunedin to confirm they had arrived at Scott Base. After a base tour they are scheduled to have dinner, their bags arriving at 7pm, and Antarctic Field Skills training starting at 845am Tuesday morning. The logistics support for Expedition 5 is provided through Antarctica New Zealand Event K060. [26 November 2012].
Expedition 5 prepares to depart for Antarctica
The fifth Antarctic expedition from the Otago Space Physics group is preparing for their trip South. Dr James Brundell, the event leader, is currently working alongside Dr Ian Whittaker, to undertaken noise tests and become familiar with some of the experimental equipment they will use when south. The team is scheduled to travel to Scott Base on Monday 26 November 2012 for a eight-day intensive working period. The logistics support, comprising air transport, accommodation, and all other on-ice support is provided through Antarctica New Zealand Event K060.
James and Ian are heading to Scott Base to work on Otago's AARDDVARK radio receiver which is located at Arrival Heights, not far from Scott Base. James was one of the two man Space Physics team who deployed this radio receiver in December 2008. The main aim for Expedition 5 is to move our experiment from one room of the New Zealand lab at Arrival Heights into a neighbouring room. In late 2010 a powerful LIDAR experiment was installed by US researchers in the room our experiment was located. The new LIDAR experiment has led to some issues for our experiment, which we hope to mitigate by moving next door. Ian and James will also undertake measurements of the VLF noise in and around the Arrival Heights area. Interested? You can read more at this webpage [13 November 2012]
More repairs made to Alberta AARDDVARK receiver
In early August 2012, the signal at the Ministik Lake AARDDVARK antenna suddenly dropped out - less than 3 weeks after we had travelled to Canada to repair it. We quickly identified the problem had been caused by a near-by lightning strike, which must have damaged the experiments electronics. Today, 9 November 2012 (NZ time) staff from the Space Physics Group from the University of Alberta went out to Ministik Lake and replaced the preamp - and the data is now flowing again. The new preamp has been upgraded to withstand lightning better in the future. We hope. This instrument has certainly had a very hard time, detailed on this webpage. [9 November 2012].
Craig and Aaron in Brazil
In early September 2012 Assoc. Prof. Craig Rodger and Space Physics PhD student Aaron Hendry travelled to Sao Paulo (Brazil) to attend the 5th VERSIM workshop, the first time the workshop had been held outside of Europe. Because of the transport links between New Zealand and Brazil they flew via the United States, which allowed us to visit the Udvar Hazy Center (Smithsonian Air and Space Museum). There is a particularly nice image on the space physics image collection of Aaron Hendry standing in front of the Space Shuttle Discovery (OV-103). During the VERSIM workshop one of Craig's presentations was recorded and put up on You Tube. People often comment on Craig's presentation style, and this is an example of him in action [6 September 2012].
Repairs made to Alberta AARDDVARK receiver
In mid-July 2012 Dr James Brundell and Assoc. Prof. Craig J. Rodger travelled to Edmonton in Canada to repair AARDDVARK antenna installed at Ministik Lake, Alberta, Canada. The antenna was installed in October 2010, and is located at a field site of the Space Physics Group from the University of Alberta. The Ministik AARDDVARK antenna also provides data to the world wide lightning location network, WWLLN. This instrument has had a hard time, detailed on this webpage. It has suffered from computer failure and the attention of the local wildlife. Craig and James headed out to repair and upgrade the instrument, so it is better suited to make continuous measurements in the next few years to support the RBSP and DSX spacecraft missions, and the BARREL balloon campaigns [21 July 2012].
James and Craig with the repaired antenna.
Postdoc Dr Ian Whittaker arrives from the UK
Dr Ian Whittaker arrived in the Space Physics group in early July 2012, taking up a Postdoctoral Fellowship position - Ian is working on energetic electron precipitation and its link to the plasmasphere, funded by the European Union FP7 project (PLASMON). W are thrilled to welcome Ian to the group, and hope to add his photo to the group website soon. [5 July 2012].
Update from Bonar Carson
Former Space Physics MSc student Bonar Carson is now living in Auckland working as a financial analysis for ASB. We have received a picture of Bonar showing him in his new work environment and looking sharp indeed. The examination process for Bonar is all over bar the corrections, and we have recently submitted a paper to the Journal of Geophysical Research based on his MSc work. Bonar is now about to feature in the Otago Physics Department publicity material, in the Graduate Profile section [12 June 2012].
Mark Clilverd visiting us from the British Antarctic Survey
