Abstract
- Remarkably, the five largest recorded sunspot groups all occurred during a period of just over five years, from 1946 February to 1951 May, during Solar Cycle 18. These are the only groups known with areas greater than 4,500 millionths of the Sun's visible hemisphere. This paper examines the white-light activity of the groups. [ABSTRACT FROM AUTHOR]
