M3.3 Solar Flare From Sunspot 1718 - April 12, 2013

   Today we had a M3.3 solar flare from sunspot region 1718 peaking at 20:38 UTC
Today's M3.3 flare comes on the heels of the M6.5 solar flare that occurred yesterday (April 11th) around sunspot region 1719 peaking at 07:16 UTC.

 

   At this time the M3 flare from today does not appear to have produced a CME. We will however be monitoring the solar images to see if we see any signs of this changing. The M6 flare from yesterday did however produce a Earth directed CME that is due to arrive sometime in the early hours of Saturday April 13, 2013 when a moderate G2 geomagnetic storm is forecasted to occurred.

Event Issue Date: 2013-04-11 11:41:59.0 GMT
CME Arrival Time: 2013-04-13 05:57:21.0 GMT
Arival Time Confidence Level: ± 6 hours
Disturbance Duration: 5 hours
Disturbance Duration Confidence Level: ± 8 hours
Magnetopause Standoff Distance: 4.8 Re

This M6 solar flare + CME occurred while sunspot region 1719 was directly Earth facing and because of this, there is a S2 solar radiation storm that was set into effect due to the energetic solar protons flying past earth
