Application of the Chromospheric Magnetograph to Active Regions
Chapter
Abstract
We show how to determine the magnetic field structure in active regions from the Ha morphology. We also show the role of the EFR (emerging flux region) as a bipolar region of velocity downflow. Finally, we point out that since all new magnetic flux emerges in strictly bipolar form, complex spot groups must result from surface interaction, hence most of the solar surface field may be produced on the surface.
