From Space Weather:
Sunspot AR1515 has grown into a behemoth more than 10 times wider than Earth. The active region is crackling with M-class solar flares and seems poised to produce even stronger X-flares in the days ahead. At least one CME is en route to Earth, and ham radio operators are reporting shortwave solar radio bursts roaring from the loudspeakers of their receivers.Remember these are just warnings. The sky isn't falling. Just a reminder to take precautions.
