Make that Three
Region 2087 produced an impulsive X1.0 solar flare Wednesday morning at 09:06 UTC. This is now the 3rd such X-Class event within the past 24 hours. A relatively faint coronal mass ejection (CME) is seen in the latest LASCO C2 coronagraph imagery. The plasma cloud appears to be blended in with an earlier CME following an M3.0 flare around the same region an hour earlier. The active region will continue to be a threat for major solar flares as it continues to rotate into a more geoeffective position. http://www.solarham.net/

Yesterday’s double X-flare may have produced a geoeffective CME after all. At first it appeared that Earth was outside the line of fire, but a closer look at the CME reveals an Earth-directed component.
A faint CME associated with the first X-flare emerging around 1200 UT. A second, brighter CME from the second X-flare quickly overtakes it, forming a “cannibal CME.” Computer models run yesterday by NOAA analysts suggest the merged storm cloud will reach Earth mid-day on June 13th. The glancing blow could spark polar geomagnetic storms. http://spaceweather.com/
