Eruptive M2.4 solar flare

Decaying sunspot region 2665 (Beta, S07W31) produced a very long duration M2.44 solar flare that is still in progress at the time of writing. Indeed a big surprise as its magnetic layout remains rather simple and that means such a solar flare was very unlikely to happen.

Early indications show that this is a very eruptive solar flare and that it has launched a coronal mass ejection. STEREO Ahead shows an expanding cloud of solar plasma on the latest imagery. No SOHO images are available yet to confirm an earth-directed trajectory but considering the location of sunspot region 2665 an earth directed portion is not impossible. More information will be posted later today.
