Sun Spots on 11-5-2013

BIG SUNSPOT TURNS TOWARD EARTH: One of the biggest sunspots of the current solar cycle emerged over the sun's eastern limb three days ago and now it is turning toward Earth. This movie from NASA's Solar Dynamics Observatory shows the approach of sunspot AR1890:AR1890 has an unstable 'beta-gamma-delta' magnetic field that harbors energy for strong explosions. So far the sunspot is quiet, but this could be the calm before the storm. NOAA forecasters estimate a 45% chance of M-class solar flares and a 10% chance of X-flares on Nov. 5th.
