SUPERNOVA 2002gy IN UGC 2701
     Further to IAUC 7972, B. Beutler and W. D. Li report the
LOTOSS discovery of an apparent supernova (mag about 17.6) on an
unfiltered CCD KAIT image taken on Oct. 16.4 UT.  The new object is
located at R.A. = 3h22m36s.45, Decl. = +9 28'22".0 (equinox 2000.0),
which is 2".8 east and 3".0 south of the nucleus of UGC 2701.  M.
Hamuy, Carnegie Institution of Washington, confirmed SN 2002gy on J
and H images taken with the Las Campanas Dupont 2.5-m telescope (+
WIRC) on Oct. 17.4.  A KAIT image taken on Oct. 9.4 showed nothing
at this position (limiting mag about 19.0).


SUPERNOVA 2002gz
     Further to IAUC 7995, W. M. Wood-Vasey, G. Aldering, P. Nugent,
and K. Li report the discovery of an apparent supernova (mag 18.3)
on unfiltered NEAT images taken with the Palomar 1.2-m Schmidt
telescope on Oct. 15.48, 15.49, and 15.50 UT (confirmed on Oct. 18
at mag 18.2).  The new object is located at R.A. = 2h34m10s.36,
Decl. = -0 53'18".2 (equinox 2000.0), which is 4" east and 1" south
of the center of the apparent host galaxy.  No point source is
visible at this location in previous NEAT images taken on Sept. 22
(limiting mag 20.2 at S/N = 5).


SUPERNOVA 2002gv
     G. Miknaitis, University of Washington, reports that a CCD
spectrum of SN 2002gv (cf. IAUC 7994), taken on Oct. 14 UT with the
Baade 6.5-m telescope (+ LDSS-2) at the Las Campanas Observatory by
K. Krisciunas, N. Morrell, and M. M. Phillips, is consistent with
that of a type-Ia supernova, approximately 10 days after maximum,
at z about 0.24.  A spectrum of its host galaxy taken on Oct. 15,
confirms a redshift of 0.25.


SUPERNOVA 2002gw IN NGC 922
     Unfiltered CCD magnitudes:  Oct. 11.633 UT, 18.3 (K. Itagaki,
Yamagata, Japan; prediscovery image; forwarded by S. Nakano, Sumoto,
Japan); 17.92, 17.8 (L. A. G. Monard, Pretoria, S. Africa).


POSSIBLE NOVA IN SMALL MAGELLANIC CLOUD
     Another broadband V CCD magnitude of this object (cf. IAUC
7995) from W. Liller, Vina del Mar, Chile:  Oct. 19.131 UT, 13.19.
Visual magnitude estimate by A. Pearce, Nedlands, W. Australia:
Oct. 18.654, 13.2.
