Sunspot AR12371 has been very busy, erupting with M-class flares that blasted coronal mass ejections (CME) toward Earth. Auroras have been seen as far south as Arizona. A June 25, 2015 flare produced a coronal mass ejection which could bathe the Earth in geomagnetic storms. [Attack of the Sun - Video Show: ] Imagery of the flare was captured by NASA’s Solar Dynamics Observatory (SDO).
