EUHFORIA predicts the Antarctic Solar Eclipse

Scientists run the EUHFORIA computer programme to have a preview of the solar eclipse of December 4. A chance to check their calculations. Fingers crossed and certainly ask the penguins.

Antartic Solar Eclipse

Let’s hope the penguins have their eclipse glasses ready. They will form most of the crowd in the Antarctic that will be able to witness a total solar eclipse on December 4. As always, the LYRA and SWAP instruments on PROBA2 are ready to observe this spectacle from their sun-synchronous orbit around Earth.

An exit in style

NOAA 2891 produced a photogenic solar eruption late on 9 November, while it was already well behind the northwest solar limb.The event was accompanied by an interesting feature, the so-called Supra Arcade Downflows (SADs).

The Day After...

The arrival and subsequent passage of a potent ICME late on 3 November left its mark on the evolution of energetic particles in the magnetosphere. Also the number of cosmic rays dipped sharply, but briefly.

We proudly present K_Bel: a new, local K-index to monitor the variations in the Earth magnetic field. It is based on data from two independent magnetometers located in the magnetic observatories of Belgium: Dourbes and Manhay.

X-class flare!

Flare-active sunspot region NOAA 2887 produced an X1 flare on 28 October at 15:35UT. The associated CME is mainly directed to the south, but an earth-directed component is visible in the latest coronagraphic images. UPDATED2!

Tracking SC25

A new STCE webpage aims to track the evolution of a number of important space weather parameters during the current solar cycle 25.

Ode to GOES

16 October 1975 marks the launch of GOES-1, the first of the GOES family. 46 years later, the new generation is still going strong.
