Description/Abstract | The history of observations of the Great White Spots on Saturn is reviewed, incluing the 1876, 1903, 1933, and 1960 outbreaks.^The spots have been used to trace zonal winds on Saturn, showing longitudinal expansion spot velocities of 30 to 45 m/s and north-south expansion velocities of about 3 m/s.^The relationship between spot activity and the Saturnian atmosphere is discussed.^A graph of insolation at the top of Saturn`s atmosphere during Great White Spot activity and photographs of the 1933 and 1960 spots are presented.^Because the trends in spot activity show a recurrence time of about one Saturnian year (29.51 yrs), it is suggested that spot activity may occur in 1989 or 1990. |
