Title

A Microfilm Atlas of Magnetic Fields in the Solar Corona

Abstract

This is a Microfilm atlas of magnetic fields in the solar corona. The original item included a text of 26 pages and 11,000 maps on 11 reels of microfilm. This Atlas contains 11,000 maps of the calculated potential (or current-free) magnetic fields of the solar corona between August 1959 and June 1970. For each solar rotation in this interval, there are two sets of maps. The first set of maps shows the geometry of the coronal magnetic field but includes field lines originating from both strong or weak fields at the photosphere. (However, no field lines are drawn from a photospheric region if the calculated field strength there is less than 0.08 Gauss.) The second set of maps shows field lines which emanate from the regions of strongest photospheric magnetic field. Each set provides one map for every 100 interval of solar longitude or 36 maps for each rotation.
