The large spot group in the middle of the disk is AR 759 and it was this group that unleashed the big CME on May 13th. The spot groups shown are from left: 763, 759, 762 and 758. 758 was visible for only a few hours after this image was taken as it rounded the farside.

John's handheld photos continue to impress as his experience and steady hand brings great results.
