COMET P/2001 CV_8 (LINEAR)
     An object that was reported as asteroidal by LINEAR (discovery
observation given below), and given the designation 2001 CV_8, has
been found by other CCD observers to show cometary activity.  M.
Hicks, Jet Propulsion Laboratory, reports that nonphotometric
images (with imperfect tracking) obtained with the 0.61-m f/16
reflector at Table Mountain Observatory by D. Esqueda, A. Esqueda,
and T. H. Ha on Feb. 4 indicate this object to be diffuse without
condensation but with a faint, 5" fan-shaped tail toward the west.
Images taken by D. T. Durig (Sewanee, TN; 0.3-m f/5.8 Schmidt-
Cassegrain telescope; moonlight and tracking problems) on Feb. 6
show the object to be more diffuse than nearby stars.  Observations
by J. Ticha and M. Tichy at Klet (0.57-m f/5.2 reflector) on Feb.
10 show the object to be diffuse with a 9" coma and a faint 15"
tail in p.a. 270 deg.

     Additional astrometry and the following orbital elements (and
an ephemeris) by B. G. Marsden appear on MPEC 2001-C24.  The
elements indicate that the comet passed about 0.14 AU from Jupiter
in Nov. 1998.

SUPERNOVA 2001T IN MCG -02-37-6
     X. J. Jiang, Y. L. Qiu, and J. Y. Hu, on behalf of Beijing
Astronomical Observatory (BAO) Supernova Survey, report the
discovery of an apparent supernova found on unfiltered images taken
with the BAO 0.6-m telescope on Feb. 6.9 (mag about 17.0) and 8.9
UT (mag about 16.8).  SN 2001T is located at R.A. = 14h32m53s.17,
Decl. = -12o58'43".6 (equinox 2000.0), which is 3".1 east and 12".6
south of the nucleus of MCG -02-37-6.  An unfiltered image of the
same field taken on 2000 June 4.7 showed nothing at this position
(limiting mag about 18.5).
