AR11476:Gamma-Delta configuration

By May 9 this huge group has evolved strong R (red) polarity spots in the large violer (V)preceding spot - a mix of opposite sign spots in the one penumbra. It is now Hale Gamma-Delta class. A salvo of GOES Class M flares are the result - though none are logged here. There were, however, several small flares along the inversion line between opposite sign spots. The area of the group is now over 1000 units.
