An X-class solar flare erupted today near sunspot 484--a remarkably fast growing active region near the sun's northeastern limb. Yesterday the spot was barely visible; now it is about 7 times wider than Earth. Because of its location near the suns's limb, today's blast was probably not Earth-directed. Sunspot 484 is, however, moving into position where it could aim solar flares and coronal mass ejections our way later this week--if solar activity continues high.
