COMET SPACEWATCH (1992h)
D. Rabinowitz, Lunar and Planetary Laboratory, University of
Arizona, reports the discovery of a comet with the moving-object
detection software on the Spacewatch telescope at Kitt Peak.
J.Scotti provides the precise positions below. The comet is
described as diffuse, with no resolvable tail, the coma being of
diameter 14" on May 1 and 17" on May 2.

SUPERNOVA 1992V IN ANONYMOUS GALAXY
C. Pollas, Observatoire de la Cote d'Azur, reports his discovery on
IIIa-J OCA Schmidt plates taken Apr. 22.9 and 26.9 UT (limiting
magnitude 21.5) of an apparent supernova of mag B = 18.0 located at
R.A. = 12h32m14s.73, Decl. = +14 50'06".2 (equinox 1950.0). SN
1992V is offset 9".7 west and 8".5 south of the bright nucleus
of a very diffuse, face-on spiral galaxy. Nothing is visible to
mag 19 (B) on Mar. 3.1 or to mag 20.5 (panchromatic film) on Mar.
10.1 exposures taken with the OCA Schmidt telescope. A star of mag
14 has end figures 05s.90, 07".7. T. Balonek, Colgate University,
confirms the existence of SN 1992V, which also does not appear on
the Palomar Sky Survey.
