SUPERNOVA 2001gc IN UGC 3375
     M. Schwartz, Cottage Grove, OR; and W. D. Li, University of
California at Berkeley, on behalf of LOTOSS (cf. IAUC 7514), report
the discovery of an apparent supernova on an unfiltered image taken
with the 0.5-m Tenagra III automated telescope on Nov. 21.4 UT (mag
about 16.2).  SN 2001gc is confirmed at mag about 16.8 on an
earlier image taken by the Katzman Automatic Imaging Telescope
under poor conditions on Nov. 19.5.  The new object is located at
R.A. = 5h55m26s.14, Decl. = +51o54'34".2 (equinox 2000.0), which is
7".3 east and 4".3 south of the nucleus of UGC 3375.  A Tenagra III
image taken on Nov. 14.4 showed nothing at this position (limiting
mag about 19.0).


SUPERNOVA 2001fz IN NGC 2280
     T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrum (range
370-750 nm) of SN 2001fz (cf. IAUC 7753), obtained by K. Rines on
Nov. 19.50 UT with the F. L. Whipple Observatory 1.5-m telescope (+
FAST spectrograph), shows it to be a type-II supernova.


COMETS C/2001 U8, C/2001 U9, C/2001 U10, C/2001 V1, C/2001 V2
     Further to IAUC 7750, D. Hammer reports his measurements of
additional Kreutz sungrazing comets found on SOHO website images by
R. Kracht (C/2001 U8, C/2001 U10), X. M. Zhou (C/2001 U9), T.
Scarmato (C/2001 V1), and A. and M. Mimeev (C/2001 V2).  All the
objects were seen in the C2 coronagraph.  According to D.
Biesecker, C/2001 U9 was a bright comet, visible from the edge of
the C3 field-of-view until it disappeared behind the C2 occulter;
it appears to have saturated the detectors in both telescopes.  The
reduced astrometry and orbital elements by B. G. Marsden appear on
the MPECs cited below.
