Sunspot AR1389 unleashed two M-class solar flares yesterday and may not be done yet. Two other sunspots, AR1386 and AR1387, also have the potential to cause a solar event; AR1387 was the source of the CME on Dec. 25th. The NOAA Space Weather Prediction Center has predicted a 40% chance of M-class flares through tomorrow.
