The Great White Spot on Saturn, named by analogy from Jupiter's Great Red Spot, is a name given to storms that are large enough to be visible by telescope from earth by their characteristic white appearance.
The phenomenon is somewhat periodic:
- 1876 first observations by Asaph Hall. He used the white spots to determine the planet's period of rotation.
- 1903 Edward Barnard
- 1933 Until recent times the most celebrated. Made by Will Hay, comic actor and amateur astronomer.
- 1960 JH Botham (South Africa)
- 1990 Stuart Wilbert
- 2006 Erick Bondoux, Jean-Luc Dauvergne
