Coming up!
KHO is part of the upcoming sounding rocket campaign named Rocket Experiment for Neutral Upwelling 3 (RENU-3). The payload is designed to measure neutral gas, ions and electrons associated with Poleward Moving Auroral Forms (PMAFs) in the dayside Cusp. The first possible launch window is 13 - 27 of November.

NEW Planeterrella!
Baptiste Katz and Olivier Falque from the University of Grenoble have installed and demonstrated our new Planeterrella reconstructed by Prof. Jean Lilensten. It's capable of creating artificial aurora just like Kristian Birkeland did back at the turn of the 19th century. View amazing displays recorded by Lotte van Hazendonk in the below links.

Asteroid impact?
Prof. II Kjellmar Oksavik strikes again on TV2 Play TikTok! He informs that the asteroid identified as 2024 YR4 discovered last Christmas, will according to calculations by NASA, luckily not hit Earth in 8 years. That is a great relief!

The Red-Sky Enigma returns
From mid-January with the return of nautical to civil twilight conditions on Svalbard, a red-purple sky color is daily observed with the rise of the Sun - even though it's way below the horizon. This effect is due to a long period of cold temperatures (-85oC) in the Stratosphere over Svalbard and the mainland. As a consequence, Polar Stratospheric Clouds (PSC) are formed, ducting and scattering the solar light into the dark illuminated polar hemisphere. The process is explained in our Red-Sky Enigma paper published back in 2005.

Is the Aurora disappearing from Svalbard?
Mikkel Breedveld and Stein Haaland points out that the magnetic pole moves in position and will consequently shift the auroral oval 5-6 km South each year if the current changes in the Earth's magnetic field continues. The question of how long we will see aurora from Svalbard is raised.
