SUPERNOVA 2001dr IN NGC 4932
     A. Dimai, Cortina d'Ampezzo, Italy, reports the discovery of
an apparent supernova (mag about 16.5) by A. Gabrjelcic, Agordo,
Italy, on images (limiting mag about 18.0) taken on Aug. 14.88 and
15.85 UT with a 0.28-m reflector (+ HiRes 1600 CCD camera) in the
course of the CROSS program.  The new object was also imaged at mag
16.6 with a 0.51-m reflector at Col Drusci on Aug. 16.83 (limiting
mag about 19.0).  SN 2001dr is located at R.A. = 13h02m39s.10,
Decl. = +50o26'39".5 (equinox 2000.0), which is 9" east and 12"
north of the nucleus of NGC 4932.  The new object is not present on
Palomar Sky Survey images.


SUPERNOVA 2001ds IN UGC 1654
     The Central Bureau has received reports that independent
discoveries have been made of a new supernova in UGC 1654 by T.
Boles, Coddenham, England (via G. M. Hurst, Basingstoke, England),
on unfiltered CCD images taken for the U.K. Nova/Supernova Patrol
on Aug. 14.999 (mag 16.2) and 16 UT (mag 16.6), and by LOTOSS (cf.
IAUC 7514; via D. J. Hutchings and W. D. Li, University of
California at Berkeley) on unfiltered CCD images taken with the
Katzman Automatic Imaging Telescope (KAIT) on Aug. 16.5 and 17.4
(mag about 18.3).  M. Armstrong, Rolvenden, England, also obtained
a confirming image on Aug. 16.972.  The LOTOSS position for SN
2001ds is R.A. = 2h10m08s.73, Decl. = +36o42'20".3 (equinox 2000.0),
which is 4".1 west and 3".6 north of the nucleus of UGC 1654.  A
KAIT image taken on Jan. 17.2 showed nothing at this position
(limiting mag about 19.0).  Boles' position end figures, averaged
from frames on two nights, are 08s.80, 20".1, or 5".0 west and 3".5
north of the galaxy's nucleus.  SN 2001ds is absent from an image
taken by Boles on 1999 Dec. 4.941 (limiting mag 18.0) and from
Palomar Sky Survey images taken in 1954, 1989, and 1992.


NOVA IN M31
     P. Martin and W. D. Li, University of California at Berkeley,
report the discovery of an apparent nova in M31 (= NGC 224) on
unfiltered images taken by the KAIT on Aug. 14.5 (mag about 17.6)
and 16.5 UT (mag about 16.8).  The nova is located at R.A. =
0h42m18s.47, Decl. = +41o12'38".9 (equinox 2000.0), which is 291"
west and 210" south of the nucleus of M31.  A KAIT image of the
same field taken on Aug. 13.5 showed nothing at this position
(limiting mag about 19.0).
