Big Sunspot AR2665 is Directly Facing Earth, any Explosions would be Geoeffective
CHANCE OF FLARES: Big sunspot AR2665 has decayed a little during the past 24 hours. Nevertheless, it still has an unstable magnetic field that poses a threat for moderately strong solar flares. NOAA forecasters say there is a 25% chance of M-class flares on July 12th. Any explosions would be geoeffective as the sunspot is directly facing our planet.
AR2665 is by far the biggest sunspot of 2017, stretching more than 120,000 km from end to end. Moreover, it has an unstable 'beta-gamma' magnetic field that harbors energy for M-class explosions. Any eruptions today would be squarely Earth-directed.
