Fantastic!

"A fast-moving stream of solar wind hit Earth on Sept. 14th, sparking an unexpectedly strong G3-class geomagnetic storm." #SpaceWeather

We couldn't have hoped for a better advertisement for this year’s public lecture series than last night's spectacular show of northern lights!

The talks will deal with all the exciting aspects in the fiery relationship between the Sun and the Earth (in German). So if you want to learn more about the Sun, the aurora borealis, the dangers of solar storms, about space weather forecasting and more, join us for

"Im Feuerwerk der Sonne" https://www.mps.mpg.de/im-feuerwerk-der-sonne

The series kicks off with the first talk by Sami Solanki on Thursday, 12 February 2026 at 19:00h in the auditorium at MPS Göttingen (OSM: https://www.openstreetmap.org/way/253918007#map=19/51.560282/9.948555)

"G4 (Severe) Geomagnetic Storm Watch for 20 January UTC-Day" by NOAA Space Weather Prediction Center SWPC - G4 (Kp=8) geomagnetic storm conditions forecast for January 20 0600-0900 UTC, favoring tonight in the Americas for aurora viewing. https://www.spaceweather.gov/news/g4-severe-geomagnetic-storm-watch-20-january-utc-day #NOAA #SpaceWeather #CME #Aurora #AuroraBorealis #AuroraAustralis

NOAA image caption:
A G4 (Severe) geomagnetic storm watch is in effect for the 20 January UTC-day due to Earth-arrival of a coronal mass ejection (CME). The CME blasted from the Sun on 18 Jan, in association with an energetic R3 (Strong) solar flare from a sunspot region near center-disk, and is anticipated to arrive at Earth as early as late 19 Jan EST to early 20 Jan. While the G4 Watch is out for the 20 Jan UTC-day, geomagnetic storm levels could range from G1-G3 (Minor-Moderate) upon CME arrival later on 19 Jan EST. CME passage is expected to continue through 20 Jan, but conditions are likely to weaken later in the day. G1 levels remain possible on 21 Jan due to residual CME related effects. Forecasters have a fair measure of confidence in timing and of CME arrival at Earth. Please continue to visit our SWPC webpage for the latest forecasts, information, and updates.
