The Uniqueness of the Geographic South Pole for the Observations of Large Scale Velocity Fields on the Sun: Some Experiences from a 120 Hours Continuous H-Alpha Patrol during January 1979

Continuous solar observations over extended periods of time with the sun at constant altitude have heretofore been unobtainable. A solar observatory at the geographic South Pole will provide continuous homogenous observations of various solar features during the austral summer months. An optical sit...
