    Tom Gehrels, Lunar and Planetary Laboratory, reports his
discovery of a comet by eye in the course of the Spacewatch program.

SUPERNOVAE 1997U AND 1997V IN ANONYMOUS GALAXIES
     B. Schmidt reports the discovery by the Mount Stromlo Abell
Cluster Supernova Search Team (cf. IAUC 6418) of two apparent
supernovae near Abell 423 on CCD images taken by S. Sabine with the
Mount Stromlo 1.27-m telescope (+ Macho Camera).  SN 1997U is
located at R.A. = 3h10m46s.25, Decl. = -12 16'04".5 (equinox
2000.0), which is 0".01 east and 0".45 north of the nucleus of the
host galaxy.  SN 1997U is visible at mR about 21.5 on V and R CCD
images taken on Jan. 2, and it was also detected on similar frames
taken on Jan. 5 and 8.  SN 1997V is located at R.A. = 3h11m43s.82,
Decl. = -12 02'11".0 (equinox 2000.0), which is 6".0 east and 0".1
north of the nucleus of the host galaxy.  SN 1997V is visible at mR
about 21.0 on V and R CCD images taken on Jan. 8, and is also
present, but 0.5 mag fainter, on similar frames taken on Jan. 5.
     Neither SN 1997U nor SN 1997V was detected on frames taken on
1996 Dec. 18.  Finding charts are available at
