(7331) Balindblad Main-belt Asteroid
Discovered on 15 October 1985 by E. Bowell at Anderson Mesa.
Named in honor of Bertil A. Lindblad (b. 1921) of the Lund Observatory, in recognition of his lifetime work on meteor orbits; his long-term effort in establishing a database for all meteor orbits, now generally used by all meteor workers; his stewardship of IAU Commission 22, which he served as president in the early 1970s; and, in particular, his contribution to starting the very successful “Asteroids, Comets, Meteors” series of conferences.
