"Geomagnetic storm level G3 watch for 16 Apr 2025" by NOAA Space Weather Prediction Center - Coronal Mass Ejection CME from the weekend will reach Earth tonight. G3 storm means forecast Kp=7 aurora tonight. But forecasts are not precise until an hour before arrival when satellites at Sun-Earth L1 (1M mi / 1.6M km away) can measure incoming solar wind. spaceweather.gov/news/g3-watch #SpaceWeather #aurora #AuroraBorealis #AuroraAustralis #astronomy

"G3 (Strong) Geomagnetic Storm Watch for 23 Mar" by NOAA Space Weather Prediction Center - The Sun erupted a coronal mass ejection (CME) expected to reach Earth on March 23 UTC at G3 storm level. That means forecasted Kp=7 for aurora down to Oregon, Idaho, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, New York and Massachusetts. spaceweather.gov/news/g3-stron #astronomy #aurora #AuroraBorealis #AuroraAustralis #CME #SpaceWeather

One more #FediWall for today's #FollowFriday: with solar cycle 25 at its maximum this year, aurorae will continue to be a thing for a while. Catch them all s.gwdg.de/FcoN6a

To be prepared for when the next aurora alert pops up, you can pick and start following accounts that are likely to make you aware of an ongoing event, so that you too can go out, take your own pictures, and share them with us? 📷

In the meantime, going back to the amazing event in May last year, we have some background reading for you [in German] at mps.mpg.de/7926227/news_public
