Photospheric magnetic field maps at solar minimum.

CR1912 (July 25 - August 22, 1996)

CR1913 (August 22 - September 18, 1996)

Photospheric magnetic field maps for Carrington rotations CR1912 and CR1913 (August-September, 1996), as measured by the National Solar Observatory at Kitt Peak. The maps show the measured photospheric field as a function of latitude (vertical axis) and Carrington longitude (horizontal axis). Red shows outward directed magnetic flux, and blue shows inward directed flux. Click the images for higher resolution pictures. This interval was part of a coordinated campaign, known as Whole Sun Month, and coincided with the minimum of the solar activity cycle.
