Large 11 part mosaic with iMerge

 While
            clouds prevented getting the lower part of this huge mosaic finished,
            the free ware iMerge did a job much better than I could even
            come close to in Photoshop. Several very interesting features
            can be seen clearly in the image below. The huge spot group at
            center is is AR1283, a massive group poised eject an Earth directed
            CME at any time. Above it is a small filament, and to its left
            a huge filament which has persisted for many days now. AR1281
            is seen on the lower right.
