Visit to BGS
In mid-June 2023 Craig Rodger travelled to the UK and visited our Solar Tsunamis research programme team members. He joined them in Edinburgh, hosted by the Geomagnetism Team at the British Geological Survey (BGS). During the visit, he was shown the historical magnetic field measurements of the 1859 Carrington event, stored in their data archive.…

First Injection Campaign
It can be challenging to measure the real world effects of Geomagnetically Induced Currents (GICs) on the electrical grid, because researchers and engineers have to wait until solar activity causes a significant geomagnetic disturbance in the Earth’s magnetic field. Having no control over when these events might happen or how extreme they can be places…

Daniel Mac Manus hands in PhD thesis
Today (4th Jan) Daniel Mac Manus submitted his PhD thesis – a great way to start 2023! Daniel has been working on his thesis research for a little under 4 years, which has involved some strong collaboration with our industry partners from Transpower New Zealand. The upshot of that was a recent paper in AGU’s Space Weather journal, looking…

GNS Installs Northlands First 8 LEMI Instruments
In October 2022, Kristin Pratscher, Wiebke Heise and Malcolm Ingham installed the first 8 LEMI instruments in Northland and the remote reference site in the Kaingaroa forest. They also scouted some sites for the next fieldtrip scheduled in mid-November 2022 and found a place to store some equipment in Auckland (a friend of Malcolm Ingham).…

Chatham Islands Festival of Science
The Chatham Islands Festival of Science brought project members from Dunedin, along with scientists from around New Zealand to the islands in mid August. The outreach team from Tūhura Otago Museum visited schools with help from the scientists as part of a jam-packed week’s worth of science focused activites. The Solar Tsunamis team were busy…

Visit to Firstgas
Project members from around New Zealand travelled to New Plymouth recently to meet with Firstgas. As part of the Solar Tsunami Endeavour Fund, research is being undertaken to help Firstgas understand what risks are posed to gas pipelines by GIC. Unlike power transmission lines, gas pipelines are not at risk of sudden catastrophic damage due…

GNS Southland LEMI Deployment
At the end of September 2021 Ted Bertrand and Wiebke Heise installed the first 8 LEMI instruments for this season in the Queenstown area. In November that year Malcolm Ingham and Wiebke Heise picked up the 8 instruments and installed them at 8 new locations in Otago, Southland and Fiordland. One site that was picked…
