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.
The M2.4 flare looks highly eruptive. STEREO Ahead shows an expanding cloud of solar plasma. Might be earth-directed. More info later today. pic.twitter.com/Y6D8ryWLHi— SpaceWeatherLive (@_SpaceWeather_) July 14, 2017
