Rapid changes in the fine structure of a coronal "Bright point" and a small coronal "active region".
Abstract
A coronal `bright point' is resolved into a pattern of emission which, at any given time, consists of 2 or 3 miniature loops (each ∼2500 km in diameter and ∼12 000 km long). During the half-day lifetime of the `bright point' individual loops evolved on a time scale ∼6 min. A small `ctive region' seemed to evolve in this way, but the occasional blurring together of several loops made it difficult to follow individual changes.
