Two moderate M-class solar flares in last 6 hours
Sunspot region about to rotate into view off the southeast limb produced an M1.7 solar flare at 23:31 UTC on October 9, 2012. Just few hours later, at 5:04 UTC (October 10, 2012) the same region produced another M-class event peaking at M1.02.
Last night we saw a G1 minor geomagnetic storming, nevertheless a good opportunity for aurora pictures. Below is a graph representing last 7 days of geomagnetic levels.

Fantastic aurora image was brought by solarham.com, this time from 21,000 feet in the air over Alberta, Canada taken by Matt Melnyk. “Here are some shots of last nights display from 21,000 feet. I am a pilot so I get a great view of the aurora from the cockpit. This was between 02:30 am and 03:30 am while flying to Fort McMurray from Edmonton at 21,000 feet.”
