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)

Za AstroBlogerPL:

PILNA AKTUALIZACJA

O ile nie jest to błąd danych mamy absolutnie ekstremalny impakt CME po 25 godzinach podróży. Siła pola magnetycznego wzrosła do 87nT, co przewyższa tę wartość i potencjał wszystkich ekstremalnych burz magnetycznych kategorii G5 ostatniego ćwierćwiecza.
Detekcja prędkości wiatru padła podobnie jak w ekstremalnych burzach 2003 roku. Gęstość powyżej 20p/cm3 sugeruje jednak napływ CME. Jeżeli wartość Bt jest realna, a kierunek Bz rozpocznie "współpracę" z magnetosferą może nas czekać największe wydarzenie od ponad dwóch cykli.

"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.
