22ND CME IMPACT: Arriving a little
later than expected, a coronal mass ejection (CME)
hit Earth's magnetic field at 0617 UT on Jan. 22nd.
According to analysts at the Goddard Space Weather
Lab, the CME strongly compressed Earth's magnetic
field and briefly exposed satellites in geosynchronous
orbit to solar wind plasma. For the next 24 hours,
Earth's magnetic field reverberated from the impact,
stirring bright
auroras around the Arctic Circle. Bjørn Jørgensen
observed this display from Tromsø, Norway:

FLARE AND CME (UPDATED):
This morning, Jan. 23rd around 0359 UT, big sunspot
1402 erupted, producing a long-duration M9-class
solar flare. The explosion's M9-ranking
puts it on the threshold of being an X-flare, the
most powerful kind. NASA's Solar Dynamics Observatory
captured the flare's extreme ultraviolet flash:
