Monster sunspot 1890 has today rotated into a direct line with Earth, raising the possibility of any geoeffective events over the next 48-72 hours. The size of 1890 has decreased some over the past few days, with a area size of 920 being reported by solen on Nov 8th.
Even with the decrease in size sunspot 1890 retained a magnetic delta structure in the southeastern section making chances high that we will see more activity from the sunspot over the next few days. NOAA forecasters are estimating a 60% chance of M-class solar flares and a 20% chance of X-flares for Nov 8th.

X1.1 Solar Flare From Sunspot 1890 - November 10, 2013
CHANCE OF FLARES: Big sunspot AR1890 has quieted since the X-flare of Nov. 8th, but this could be the calm before the storm. The sprawling Jupiter-sized sunspot has a 'beta-gamma-delta' magnetic field that harbors energy for strong flares. NOAA forecasters estimate a 50% chance of M-class flares and a 20% chance of X-flares on Nov. 10th. credit: Spaceweather.com
