The return of the Red-Sky Enigma

We suspect unusually cold conditions in the Stratosphere, leading to the formation of ice clouds. Even under nautical twilight - when the Sun is 10 degrees below the horizon - these clouds duct sunlight towards us. This phenomenon appears in our camera systems as reddish illumination on the surrounding mountain slopes. The image referenced here is taken from KHO toward Hiorthamn. The effect is explained in our Red-Sky Enigma paper published back in 2005.

Isar Aeorospace second test!

A new milestone is approaching with Andøya Space preparing for a second attempt by Isar Aerospace to launch the Spectrum rocket, designed to carry satellites into orbit. Expectations are high that this launch will succeed after the previous setback. Our Professor II, Kjellmar Oksavik, was interviewed by TV2 and expressed great enthusiasm - signaling the start of an exciting new chapter in Norway's space endeavors.

Major update!

The Aurora Forecast apps are now upgraded. They are more standalone with minimum server dependency. A new way to seek satellites and forecasts are implemented to meet future standards of communication.

The drift in position of the geomagnetic poles are also improved and up to date, an effect that is detected by our all-sky cameras. The net result is a major upgrade in performance and accuracy of the app.
