SUPERNOVA 2001az IN UGC 10483
T. Puckett and M. Peoples, Mountain Town, GA, report the discovery
of an apparent supernova (mag 17.1) on an unfiltered CCD frame
(limiting mag 19.2) taken with the Puckett Observatory 0.30-m
automated supernova patrol telescope on Apr. 27.39 UT.  SN 2001az
is located at R.A. = 16h34m27s.71, Decl. = +76o01'46".8 (2000),
which is 4".9 west and 0".3 north of the centre of UGC 10483.  The
new object was also present on an unfiltered CCD frame taken on
Apr. 28.16, but it does not appear on multiple unfiltered images
taken by Puckett from 1999 Aug. to 2000 May, and it does not appear
on Palomar Sky Survey images taken on 1994 June 2, 1992 Apr.10
(limiting mag about 21.0), and 1955 May 20 (limiting mag about
19.7).

SUPERNOVA 2001ba IN MCG -05-28-1
R. Chassagne, Ste. Clotilde, Ile de Reunion, reports the discovery
of an apparent supernova (mag about 15.9) on unfiltered CCD images
taken with a 0.3-m telescope on Apr. 27.8 and 28.7 UT. SN 2001ba is
located at R.A. = 11h38m01s.76, Decl. = -32o19'51".0 (2000), which
is 18".7 east and 21".8 south of the nucleus of MCG -05-28-1. An
image of the same field taken on Feb. 19.9 showed nothing at this
position (limiting mag about 18).

SUPERNOVA 2001bb IN IC 4319
M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS, report the discovery
of an apparent supernova on unfiltered images taken with the 0.5-m
Tenagra III automated telescope on Apr. 29.3 (mag about 16.5) and
30.2 UT (mag about 16.3).  SN 2001bb is located at
R.A. = 13h43m25s.31, Decl. = -29o48'13".1 (2000), which is about
16".8 west and 1".4 south of the nucleus of IC 4319.  An image
taken by the Katzman Automatic Imaging Telescope on Apr. 15.3
showed nothing at this position (limiting mag about 18.5).

SUPERNOVAE 2001bc, 2001bd, 2001be
E. Cappellaro, G. Altavilla, S. Benetti, A. Pastorello, and M.
Turatto, Osservatorio di Padova; A. Clocchiatti, Pontificia
Universidad Catolica de Chile; I. J. Danziger and P. Mazzali,
Osservatorio di Trieste; and F. Patat, European Southern
Observatory (ESO), report the discovery of three new supernovae on
CCD frames taken during a search performed with the ESO/MPI 2.2-m
telescope (+ Wide Field Imager).  The supernovae were identified by
subtracting reference images taken with the same equipment during
1999.
