On March 6, 2012 we captured this 4-panel mosaic of our daytime star.
This image shows the massive sunspot 1429 to the upper left, with
sunspot 1430 just below, and sunspot 1428 over to the right. At the
very bottom of this shot is a neat, horseshoe-shaped filament and along
the solar limb are many great prominences. Several plages are visible
in this image as well.
