6845 Mansurova           Discovered 1976 May 2 by N. S. Chernykh at the Crimean Astrophysical Observatory.
Named in memory of Kira Sergeevna Mansurova (1931-1990), an astronomer in Irkutsk known for her observations with the zenith telescope. She was director of the Astronomical Observatory of Irkutsk University for many years and lecturer of astronomy at the University and Pedagogical Institute in Irkutsk. An active popularizer of astronomy, she published a number of works on astrometry and methods of teaching astronomy.
