Colas, Institut de Mecanique Celeste, Paris, and Observatoire du Pic du Midi, reports the discovery by Robin Chassagne, Sainte Clotilde, Ile de Reunion, of an apparent supernova in NGC 4965 at magnitude 14.1 CCD (unfiltered) on Mar 8.03 UT. Colas confirmed the presence of the object at CCDR magnitude 14.5, and noted that it does not appear on the Digital Sky Survey down to about magnitude 21. Colas reported the position of Supernova 2000P, located 16" east and 21" south of the center of NGC 4965, as: R.A. = 13h 07m 10.53s Decl. = -28 degrees 14' 02.5" (epoch 2000) An AAVSO Alert Notice containing more information on the supernova and an AAVSO preliminary chart will be issued on Monday, March 13. Congratulations to Robin Chassagne on discovering this apparent supernova! Please monitor this supernova and other variable stars closely and phone, fax, or e-mail your observations to the AAVSO. ---------------------------------------------------------------------------- 0744-23 BV PUPPIS The dwarf nova type (SS CYG subclass) cataclysmic variable BV PUP is in outburst, as indicated by the following observations: AAVSO Observer AAVSO Observer UT Mag.
