SUPERNOVA 2001dt IN UGC 12558
W. D. Li, University of California at Berkeley, reports the
discovery by LOTOSS of an apparent supernova (mag about 18.2) in
unfiltered images taken with the Katzman Automatic Imaging
Telescope (KAIT) on Aug. 23.4 and 24.4 UT.  The new object is
located at R.A. = 23h22m19s.17, Decl. = +50o09'25".3 (2000), which
is 1".3 west and 8".0 south of the nucleus of UGC 12558.

SUPERNOVA 2001du IN NGC 1365
R. Evans, Hazelbrook, N.S.W., reports his visual discovery with a
0.31-m reflector on Aug. 24.7 and 25.7 UT of an apparent
supernova (mag about 14.0) located about 90" west and 10" south of
the nucleus of NGC 1365, and about 20" west of a foreground star of
mag about 15.5.  Evans adds that the new object was not seen on
Aug. 23.7 under poorer conditions.  A confirming CCD image obtained
by G. Bock and P. Marples (Edens Landing, Queensland; 0.25-m
Schmidt-Cassegrain reflector) shows SN 2001du at mag about 14.1 on
Aug. 24.79, and Bock provides the following approximate position
for the new object:  R.A. = 3h33m28s.7, Decl. = -36o08'32" (2000).
M. Salvo and B. Schmidt, Australian National University (ANU);
M. Ashley and A. Phillips, University of New South Wales (UNSW);
and C. Stubbs, University of Washington, report that SN 2001du is
present at V = 14.8 +/- 0.5 on a prediscovery CCD image taken with
the UNSW Automated Patrol Telescope at Siding Spring on
Aug. 23.81.  It also appears at V = 15.2 +/- 0.1 on images taken
by P. Francis (ANU) with the Mt.Stromlo 1.9-m telescope on
Aug. 25.65.

SUPERNOVA 2001dv IN MCG +09-27-71
T. Puckett, Mountain Town, GA; and D. George, Ottawa, ON,report
the discovery of an apparent supernova (mag 18.5) on an unfiltered
CCD frame (limiting mag 20.0) taken with the Puckett Observatory
0.60-m automated supernova patrol telescope on Aug.23.15 UT.
SN 2001dv is located at R.A. = 16h44m56s.04, Decl. = +51o15'25".8
(2000), which is 3".0 east and 5".8 south of the centre of
MCG +09-27-71.  The new object was confirmed on CCD frames taken
on Aug. 24.19 with a 0.40-m reflector by J. Newton, Osoyoos, BC.

V2275 CYGNI (=NOVA CYGNI 2001 No 2)
N.N.Samus of the Institute of Astronomy, Moscow, who is
responsible for the compilation of the catalogues of variable
stars, advises that the object Nova Cygni 2001 No 2 has now
been designated V2275 Cygni.

Mike Collins adds that two good slides taken on 2001 August 17
do not show this nova:
