High HSI compression ratio
Mars 24, 2021
Erasmu+ Trainee Adrienne Esmeralda Oudijk has published her work on Hyper Spectral Imaging (HSI) compression. The spectral data cube is compressed by a factor of 10-5 with minimum loss of spatial resolution and spectral signature.
See IEEE Whispers paper and video presentation.
Pulsating aurora and O3?
Mars 12, 2021
Our PhD candidate Fasil Tesema Kebede has published work on how high energetic electron precipitation causing pulsating aurora may affect upper atmospheric chemistry and ozone destruction.

Space Hurricane!
February 22, 2021
Our very own Director Prof. Jøran Idar Moen and Adjunct Prof. Kjellmar Oksavik at UNIS have together with an international team discovered a polar ionospheric Space Hurricane, which is published in Nature. This discovery sheds new light on how Earth is coupled to space.

Aurora Forecast 3D Demo
January 30, 2021
The Aurora Forecast 3D is a tool to track down where the aurora is located in the sky from any location on planet. It renders Earth in 3D with rotation and scaling at your fingertips. This video demonstrates the app.

Day/Nightside aurora?
December 29, 2020
Our very own Professor Dag Lorentzen explains the difference between dayside and nightside aurora. This article was also published in the local news paper Svalbardposten. See norwegian translation here.

Master Lidia Luque!
December 2020
Congratulation to Master Lidia Luque! She investigated ionospheric signatures of energy input and turbulence in the polar ionosphere using the spectral width parameter measured by the SuperDARN radar (which been used as a proxy for ionospheric turbulence). Lidia examined specific cases of high spectral width and linked them to signatures of energy input into the polar ionosphere using the EISCAT radar and KHO optics. Read thesis here.
BACC #5 operational!
December 18, 2020
We are very happy to welcome the Tromsø Geophysical Observatory (TGO) at UiT The Arctic University of Norway to join the Boreal Aurora Camera Constellation (BACC) with camera number 5. It is installed and on-line today at the old Skibotn Observatory.

Interactive app
December 10, 2020
Version 6.9 of the Aurora Forecast 3D app now includes detailed target identification. Star constellation, planet, satellite and location information are linked to the Web. The main purpose is to create an interactive learning experience.
