(8009) Beguin Main-belt Asteroid
Discovered on 25 January 1989 by C. Pollas at Caussols.
Named in honor of the family of the discoverer's wife, Monick, on the occasion of her 50th birthday. She teaches in infant school. The discoverer's father-in-law, Pierre Béguin, a retired agricultural engineer, keeps his interests alive by traveling around the world, always curious for more knowledge. The word Béguin, or “flirtation” in English, gives rise to the vigorous dance of the French West Indies, the beguine.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
