#NOAA #SpaceWeather alert data says their satellites detected geomagnetic storm conditions rising to Kp=8. Where it's dark, #aurora should be beginning now. Others wait until dark, if it lasts long enough at your latitude. #AuroraBorealis #AuroraAustralis #astronomy "G4 (Severe) Geomagnetic Storming Observed" alert from #NOAA. #Aurora/#AuroraBorealis/#AuroraAustralis at Kp=8 expected farther from the poles than usual. https://www.spaceweather.gov/news/g4-severe-geomagnetic-storming-observed-0 #SpaceWeather "Solar Protons" by @XKCD comic - All the lights we see in the sky from #aurora are particles from solar wind impacting molecules in Earth's upper atmosphere, a visible show of how Earth protects its life. https://xkcd.com/2997/ #astronomy |
Looking at the #NOAA #SpaceWeather alert feed, there's a lot of activity from the latest Coronal Mass Ejection (CME). #astronomy #Aurora #AuroraBorealis #AuroraAustralis
