The Outer Solar Corona as Observed from Skylab: Preliminary Results

Abstract

The white-light coronagraph experiment has made frequent, periodic observations of the solar corona from 1.5 R0 to 6.0 R0 during the Skylab mission, and these observations will permit the determination of the three-dimensional extent of coronal forms. There are several time scales on which visual changes in coronal structures occur, ranging from approximately one-half rotation to less than hours. A number of events corresponding to the shortest time scale - coronal transients - cause major restructuring of the corona. Subject headings: corona, solar - solar wind
