This dataset contains images of daily sunspot drawings from the Mount Wilson Observatory. The sunspot record has been drawn every sunny day at the 150 ft. tower on Mount Wilson since January 4, 1917. Volunteer Steve Padilla, who worked there for many years as an UCLA solar astronomer, keeps this invaluable record going. The spots are hand drawn in pencil, and are marked with magnetic field strength data. It is the longest continual record of sunspot activity with magnetic data ever made.
