COMETS C/2001 U1, C/2001 U2, C/2001 U3, C/2001 U4, C/2001 U5
     Further to IAUC 7741, D. Hammer reports measurements of
additional sungrazing comets visible in the C2 coronagraph and
found on SOHO website images by X. Leprette (C/2001 U1, C/2001 U2),
S. Hoenig (C/2001 U3, C/2001 U4), and M. Boschat (C/2001 U5);
C/2001 U3, C/2001 U4, and C/2001 U5 were also seen in C3 images.
The reduced astrometry and orbital elements by B. G. Marsden appear
on the MPECs cited below.

     An apparently asteroidal object discovered on Oct. 29 by
LINEAR, posted on the NEO Confirmation Page due to its unusual
motion, has been found to be cometary by J. Ticha and M. Tichy
(Klet, diffuse with "a slight coma" on Nov. 3.8 UT) and by R.
Trentman (Louisburg, KS, Nov. 6.3).

The available astrometry, together with the following parabolic
orbital elements and an ephemeris, appear on MPEC 2001-V27.

SUPERNOVA 2001fu IN MCG -03-23-11
     W. D. Li reports the discovery by LOTOSS (IAUC 7514) of an
apparent supernova (mag about 15.1) in unfiltered images taken with
the Katzman Automatic Imaging Telescope on Nov. 5.5 and 6.5 UT.  SN
2001fu is located at R.A. = 8h52m16s.58, Decl. = -17o44'29".8
(equinox 2000.0), which is 25".1 west and 10".6 north of the
nucleus of MCG -03-23-11.  A KAIT image taken on Apr. 15.3 showed
nothing at this position (limiting mag about 19.0).
