SUPERNOVA 2002hw IN UGC 52
     M. Schwartz and W. Li report the LOTOSS (cf. IAUC 7906)
discovery of an apparent supernova on unfiltered images taken with
the 0.8-m Tenagra II automated telescope on Nov. 9.2 (mag about
16.8) and 10.2 UT (mag about 16.6).  SN 2002hw is located at R.A. =
0h06m49s.06, Decl. = +8 37'48".5 (equinox 2000.0), which is 6".7
west and 6".0 north of the nucleus of UGC 52.  A KAIT image from
Nov. 2.2 showed nothing at this position (limiting mag about 19.0).


SUPERNOVAE 2002gz AND 2002ho
     A. V. Filippenko, R. Chornock, and S. Jha, University of
California, Berkeley; and B. Barris, University of Hawaii, write:
"Inspection of CCD spectra (range 400-1000 nm), obtained on Nov. 9
UT with the Keck II 10-m telescope (+ ESI), shows that SN 2002gz
(IAUC 7996) is indeed a supernova, but its spectral classification
is uncertain at this time.  It most closely resembles type II, with
a blue continuum and unusually broad undulations at the approximate
positions expected of hydrogen Balmer lines and O I 777.4-nm.
Moreover, there may be He I absorption superposed on the H-alpha
emission, so perhaps its spectral type is actually IIb.  The
redshift of the host galaxy is 0.085, based on narrow emission
lines from adjacent H II regions.  SN 2002ho (IAUC 8011) is of type
Ic, within a few weeks past maximum brightness; the Ca II near-
infrared triplet exhibits an especially prominent and broad P-Cyg
profile."


POSSIBLE NOVA IN CEPHEUS
     Seiichi Yoshida, Ibaraki, Japan, reports (together with J.
Greaves, Northampton, East Midlands, U.K.; and K. Kadota, Ageo,
Saitama, Japan) his discovery, in the course of the Multitudinous
Image-based Sky-survey and Accumulative Observations Project, of a
new variable star on unfiltered CCD images taken with a 500-mm
camera lens by N. Ohkura, Okayama, Japan, on 2001 Sept. 19.56 (at
mag 12.7) and Nov. 10.45 UT (mag 14.3).  The new object is located
at R.A. = 22h58m09s.12, Decl. = +66o21'12".4 (equinox 2000.0).
Nothing appears at this position on Palomar Sky Survey plates or
Digitized Sky Survey images.  Unfiltered CCD images taken by T.
Muramatsu (Fukushima, Japan) on 2002 Oct. 25.51 with a 0.65-m
reflector show this object at mag about 20.  Images taken by
others (including A. Takao and M. Collins) show nothing to mag 12.3
on 2001 Sept. 16 and 17 and to mag 13.0 on 2001 June 28 and Oct. 8.
