39741 Komm           Discovered 1997 Jan. 9 by R. Tucker at Goodricke-Pigott Observatory.
Rudolf Walter Komm (b. 1957) has contributed substantially to the study of solar activity. His studies include tracing the movements of active regions, measuring fluctuations in solar oscillations and determining flows in granulation. Komm has also developed several innovative methods of time-series analysis.
