The Polar Magnetic Fields of July and August 1968
Abstract
Observations of the polar magnetic fields were made during the period July 3-August 23, 1968, with the Mt. Wilson magnetograph. The scanning aperture was 5″ × 5″. The magnetic field was found to be ofS polarity near the heliographic north pole and ofN polarity near the south pole. At lower latitudes the polarity was the opposite. The polarity reversal occurred at a latitude of about +70° in the north and -55° in the south hemisphere. This coincides with the position of the polar prominence zones at that time. The observations indicate that the average field strength at the south pole was well above 5 G.
