6619 Kolya           Discovered 1973 Sept. 27 by L. I. Chernykh at the Crimean Astrophysical Observatory.
Nikolaj Stepanovich Chernykh (1931-2004) was chief, beginning in 1965, of the CrAO-ITA group of observers of minor planets. He himself discovered 536 minor planets and two comets, and he participated in astronomical observations of distant spacecraft and laser ranging of the moon.
