S. Chernykh at the Crimean Astrophysical Observatory. Hermann Mucke (b. 1935), director of the Urania Sternwarte and planetarium in Vienna, is well known for his work in ephemeris astronomy and the theory of astronomical phenomena. He has contributed much to the astronomical education of schoolchildren and adults. The name was suggested by V. K. Abalakin.
