Prominences on May 30, 2012

A stack of 188 frames captured with a Microsoft Lifecam and Coronado PST, this image shows some dramatic prominence activity on the sun's limb.  Note also the brilliant spot in the one o'clock position.  This spot was very bright, visually, and matter was streaming out of it.  If you click to get the full-size image, you can see this matter in the dark sky above the spot.  A couple of small clouds that appeared to be detached could be clearly seen visually; they are just about visible in this image.
