There were multiple solar prominences visible on the Sun this afternoon, however a series of three in one group stood out as particularly spectacular (right side in this photo). Reports from previous days told of a single huge arching prominence at this same location on the solar disk.

The bright region visible in the lower part of the solar disk is Plague surrounding Sunspot 1056 - a small sunspot by most standards.
