COMET 2001 W2
     S. Nakano, Sumoto, Japan, reports the discovery of a comet
by A. Asami on CCD images taken with the Bisei Spaceguard Center
0.50-m f/2.0 reflector in the course of the "Bisei Asteroid
Tracking Telescope for Rapid Survey" program.  Additional
observations were reported following posting on the NEO
Confirmation Page:

SUPERNOVA 2001gb IN IC 582
     M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report
the discovery of an apparent supernova on an unfiltered image taken
with the 0.5-m Tenagra III automated telescope on Nov. 20.5 UT (mag
about 16.8).  SN 2001gb is confirmed at mag about 18.2 on an
earlier image taken by the Katzman Automatic Imaging Telescope
(KAIT) on Nov. 11.5.  The new object is located at R.A. =
9h59m00s.96, Decl. = +17o49'12".4 (equinox 2000.0), which is about
10".8 east and 11".1 north of the nucleus of IC 582.  A KAIT image
taken on Apr. 24.3 showed nothing at this position (limiting mag
about 19.0).
