14643 Morata           Discovered 1998 Nov. 24 by R. Roy at Blauvac.
Didier (b. 1954) and Stephane (b. 1977) Morata observe with a 0.30-m telescope from Martigues, in southern France. They have discovered novae in M31 and minor planets and are now undertaking spectroscopy of Be-type stars. Stephane is studying physics, and Didier is a chemist and editor of the magazine CCD et telescope.
