INCOMING CME: Active sunspot 1401 erupted yesterday, Jan. 19th around 16:30 UT, producing an M3-class solar flare and a full-halo (coronal mass ejection CME). The Solar and Heliospheric Observatory recorded the cloud expanding almost directly toward Earth: Analysts at the Goddard Space Weather Lab say strong geomagnetic storms are possible when the cloud arrives this weekend. Their animated forecast track predicts an impact on Jan. 21st at 22:30 UT (+/- 7 hrs). Aurora alerts: text, voice. The cloud is also heading for Mars, due to hit the Red Planet on Jan. 24th. NASA's Curiosity rover, en route to Mars now, is equipped to study solar storms and might be able to detect a change in the energetic particle environment when the CME passes by.

So it arrives here at 5:30pm Eastern standard time? I think that UT (Coordinated Universal Time) is the effectively the same as GMT (Greenwich Mean Time).
This should cause the Aurora Borealis to flash unremittingly. ;)

Any idea which side of the planet will receive the direct hit?
I did notice a lot of static on a cell phone call a few minutes ago. It would seem that the Pacific and Asia will get most of this little blast. I'm not sure how long it will last but I'm thinking less than a day.
The eruption took place at January 19, 2012, at around 16:30 UTC (12:30 CST). The image above shows the full-halo CME, or expanding cloud from the sun.
16:30 would be 11:30AM EST (UTC -5)
You're right. I added instead of subtracting. I haven't heard a lot of reporting on this story. You'd think the media would stir some interest by recounting the 1859 Carrington storm.

The sun is turning into a real hazard. I'm thinking we're going to have to nuke it from orbit.

Mike Flaherty: Yeah, it's been there a long time. I wish I knew which corner.
