COMET P/2001 TU_80 (LINEAR-NEAT)
     An object independently discovered and reported as nebulous
with a 3" coma by NEAT at Palomar on Nov. 16.5 UT has been
identified by G. V. Williams, Minor Planet Center, with an
apparently asteroidal object reported on Oct. 13 and 17 by LINEAR
(m_2 = 19.8; discovery observations on MPS 39482) and on Oct. 19 by
NEAT at Haleakala (MPS 40840), from which an apparently routine
minor-planet orbit was computed (MPEC 2001-V35).  Following posting
on the NEO Confirmation Page, P. Kusnirak at Ondrejov found the
comet to be moderately condensed with a 0'.3 coma on CCD images
taken on Nov. 17.2 with a 0.65-m f/3.6 reflector.

SUPERNOVA 2001fz IN NGC 2280
     Y. L. Qiu and J. Y. Hu, Beijing Astronomical Observatory
(BAO), report the discovery by BAO Supernova Survey of an apparent
supernova in unfiltered images taken with the BAO 0.6-m telescope
on Nov. 15.8 (when the object was at mag about 17.4) and 16.7 UT
(mag about 17.0).  SN 2001fz is located at R.A. = 6h44m50s.26,
Decl. = -27o37'12".7 (equinox 2000.0), which is 15".8 east and
66".1 north of the nucleus of NGC 2280.  An image taken with the
same telescope on Nov. 8 showed no star at this position (limiting
mag 18.0).


COMET P/2001 Q6 (NEAT)
     Total visual magnitude estimates:  Oct. 23.08 UT, 11.0 (K.
Sarneczky, Agasvar, Hungary, 0.44-m reflector); Nov. 5.75, 10.9
(R. J. Bouma, Groningen, The Netherlands, 0.25-m reflector); 10.57,
10.8 (Y. Nagai, Yamanashi, Japan, 0.32-m reflector).
