Investigation of dynamical processes in the solar corona on 30th June, 1973.
Abstract
High-resolution photographs of the solar corona obtained during a solar eclipse at two widely spaced points (time difference of 80 to 90 min between the photographs) are analyzed. It is shown that following processes can occur during one hour in a solar corona whose global structural characteristics are maintained during this period: the formation and decay (or pronounced brightness variations) of such medium-scale formations as polar rays, coronal jets, etc.; formation and decay of distinct interfaces in the coronal structure; pronounced shifts of coronal structures at speeds of several kilometers per second; and separation of solar plasma concentrations, and their ejection from the sun.
