ASTEROIDS NAMED AFTER LEONID MAC PARTICIPANTS
The following citations about two new minor planets were published in a recent
Minor Planet Ciruclar 47170 (20.11.2002). The asteroids were discovered by
Petr Pravec of Ondrejov Observatory, who provided the text below.
(42924) Betlem = 1999 TJ2
Discovered 1999 Oct. 2 at Ondrejov.
Hans Betlem (b. 1954), Dutch amateur
meteor astronomer and founder of the Dutch Meteor Society,
is well known for his photographic observations of major
meteor streams and has published many precise trajectories
and orbits of meteors. He has organized several successful
Leonid expeditions.
(42981) Jenniskens = 1999 TY224
Discovered 1999 Oct. 2 at Ondrejov.
Peter Jenniskens (b. 1962), meteor astronomer of
NASA Ames, organized several successful airborne missions
(Leonid multi-instrument aircraft campaigns) to observe the
Leonid returns from 1998 to 2002. He has substantially
improved our knowledge of the behavior of meteor streams.
