Giant Sun Spot Turns Toward Earth – More Large Flares Possible (VIDEO)

Active Region (AR) 1302 is slowly coming into position where it directly faces the Earth. The region contains a “behemoth” sunspot — several times larger than the Earth — named sunspot 1302.

The sunspot has already been the source of two ‘X-class’ solar flares (‘X’ signifying the most extreme known); the first, measuring an X1.4, on September 22, and the second, an X1.9, coming just three days later on Sept. 24. Are more X-class flares on the way, and on their way towards Earth?

Our Sun is experiencing the most prolonged period of minimal sunspot activity in nearly a century. The puzzling absence of these spots, whose build-up commonly signals the occurrence of large solar storms and flares, has space scientists and solar physicists searching for explanations.
