Galád and A. Pravda at Modra. Ladislav Košinár (b. 1929), mentor of amateur astronomy in Slovakia, founded the astronomical observatory in Sobotište in 1972. Long-time chairman of the Slovak Union of Amateur Astronomers, he is now an honorary member of the SUAA and of the Slovak Astronomical Society. The name was suggested by P. Rapavý.
