1981 EV20. Discovered 1981 Mar. 2 by S. J. Bus at Siding Spring.

Named in honor of David G. Schleicher of the Lowell Observatory for his many contributions to the physical study of comets. An enthusiastic observer, Schleicher has pursued spectroscopic and spectrophotometric investigations of cometary comae using a variety of ground-based telescopes and the International Ultraviolet Explorer satellite. Theseies of comets and the identification of a number of peculiar objects with clearly anomalous relative abundances. Schleicher played a key role in the discovery of Comet Halley's periodic variability and in the subsequent interpretation of this behavior in terms of nuclear rotation. In addition to his observational research, Schleicher's detailed calculation of the fluorescence efficiency of OH has been extremely important to the analysis of cometary spectra. (M 18452)
