The Topological Association of Hα Structures and Magnetic Fields
Abstract
The topological associations between Hα structures and magnetic fields are examined for an active region observed on two different dates. The structures seen in the on and off band of Hα filtergrams are compared with the contour maps of magnetic fields at the level of magnetogram observations. Similar comparisons are made also with the configurations of force-free magnetic lines of force at various heights evaluated with the use of formulations developed previously by Nakagawa and Raadu (1972).
