A large sunspot region is about to rotate onto the earth-facing disk

Out of nowhere yesterday we were surprised by M-class solar activity. A sunspot region that is hiding behind the north-east limb started flaring and kept the X-ray flux above the M-class threshold for about three and a half hours! Three peaks were officially recorded: M1.2 M1.9 and M2.2. Multiple coronal mass ejections left the Sun following this activity but of course none are directed towards Earth.
