6811 Kashcheev           Discovered 1976 Aug. 26 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Named in honor of Boris Leonidovich Kashcheev (b. 1920), professor of radioelectronics at Kharkov Technical University, researcher in the physics and dynamics of meteors. In 1956 he founded the laboratory for the exploration of meteors by radio techniques. He was the chief designer of MARS, the first automatic meteor radio system in Ukraine. More than 20 million meteors were detected with this system during 1972-1978, and many thousands of meteor orbits were determined and studied. He was also chair of the Meteor Commission of the Soviet Geophysical Committee.
