100940 Maunder           Discovered 1998 June 28 by E. W. Elst at the European Southern Observatory.
Edward Walter Maunder (1851-1925), a British astronomer, was the driving force in the foundation of the British Astronomical Association. He is well-known for discovering a prolonged minimum in solar activity from 1645 to 1715, corresponding with lower than average European temperatures.
