An “extreme” geomagnetic storm, resulting from yesterday morning’s massive X17 solar flare, is still in progress. Last night, auroras were seen as far south as Georgia, California, New Mexico, Arizona, Texas, and Oklahoma — and tonight could be a repeat performance. The planetary K-index remains at its highest level, 9, and Northern lights are being seen right now in England and Ireland, according to SpaceWeather.com.

Meanwhile, another extremely strong solar flare — this one rated X11 — erupted today, creating the potential for spooky Halloween auroras!

UPDATE: The ongoing space storm has disrupted a Japanese satellite.
