ACTIVE SUNSPOTS: There are two of them. Normal sunspot AR3089 and perpendicular sunspot AR3088 both pose a threat for strong solar flares. NOAA forecasters estimate a 20% chance of M-class flares and a 10% chance of X-flares today.

NOAA forecasters say there is a 50-50 chance it will hit Earth on Aug. 29th. The glancing blow, if it occurs, could spark a minor G1-class geomagnetic storm with auroras around the Arctic Circle.
