A second M-class solar flare erupted today peaking at M1.6 at 19:28 UTC (November 20, 2012). Data is still coming in but it looks like it originated from Earth directed Region 1618, a Betta-Gamma class Active Region capable of producing strong solar flares.
We already had two C-class events from this region today. SWPC recorded C1.6 at 13:51 UTC and C3.1 at 15:29 UTC.
A moderate solar flare reaching M1.7 peaked at 12:41 UTC on November 20, 2012. This event originated from Active Region 1611 located on northwest limb and was not Earth directed.
