Saturn observed on 3 August 1933. The drawing and text are by the British comedian and amateur astronomer William Thomson Hay (1888-1949). He is recording here his most famous observation, that of a white spot on Saturn. This spot, most probably a storm system of some kind in the clouds of Saturn, lasted for a few months and then faded away. Observations of the spot allowed accurate measurements of the Saturn's equatorial rotation rate. Hay, who lived in London, had become a fellow of the Royal Astronomical Society in 1932. Most of his observations were of the positions of comets.
