Expanding active-region loops seen by SXT on 22 April 1992. The time sequence, from top to bottom, is 24 minutes in duration (03:39:45 to 04:13:53). In these images south is to the top, west to the right. The brighter loops near the centers of the images appear to be interacting by magnetic reconnection as they slowly brighten. The fainter loops near the top are expanding with an apparent velocity of about 40 km/sec. The larger loop seen in the center panel shows a definite twisted configuration. This is an especially clear (and fast!) example of the common tendency of magnetic loops in solar active regions to expand outwards.
