Rapid changes in the fine structure of a coronal 'bright point' and a small coronal 'active region'

A coronal bright point is resolved into a pattern of emission which, at any given time, consists of 2 or 3 miniature loops (each approximately 2500 km in diameter and approximately 2000 km long). During the half-day lifetime of the 'bright point' individual loops evolved on a time scale approximately 7 min. A small 'active region' seemed to evolve in this way, but the occasional blurring together of several loops made it difficult to follow individual changes.
