woensdag 5 augustus 2026 15:18 UTC

On August 12, 2026, Europe will witness one of the most impressive astronomical events of the 21st century: a total solar eclipse. For amateur astronomers, physicists, and science enthusiasts, this is a rare opportunity to experience a classic yet seldom-seen celestial phenomenon. For Space Weather geeks like us it's a rare opportunity to see the solar corona without having to look on coronagraph imagery. Find out all about it here!

X1.1 solar flare, G2 watch

woensdag 1 juli 2026 16:05 UTC

We kick of the month of July with some nice solar activity! Sunspot region 4479 has been growing nicely and is now a complex Beta-Gamma-Delta region which yesterday at 20:50 UTC erupted with an X1.1 (R3-strong) solar flare. The solar flare was eruptive and launched a coronal mass ejection into space.

CME impact! S4 solar radiation storm

maandag 19 januari 2026 20:41 UTC

Impact! We just saw the arrival of the coronal mass ejection that was launched during yesterday's X1.9 solar flare. This means it took the CME only 25 hours to travel from the Sun to Earth. That is fast considering most CMEs take two to four days to travel this distance!
