COMET C/2002 B3 (LINEAR)
     F. Shelly, Lincoln Laboratory, Massachusetts Institute of
Technology, reports that an apparently asteroidal object discovered
by LINEAR on Jan. 26 (and placed on the NEO Confirmation
Page) was found to show a clear tail in p.a. about 330 deg on Feb.
11.09 UT.  T. B. Spahr, Harvard-Smithsonian Center for Astrophysics,
reports that CCD images taken with the 1.2-m reflector at Mt.
Hopkins on Feb. 12.13 show the object to be very faintly diffuse
with a faint extension in p.a. 315 deg.

     The available astrometry, the following parabolic orbital
elements, and an ephemeris appear on MPEC 2002-C81:

     T = 2002 Jan. 31.518 TT          Peri. = 124.493
                                      Node  = 289.526   2000.0

SUPERNOVA 2002ap IN M74
     Y. Yoshii, T. Minezaki, T. Aoki, K. Enya, M. Doi, and K.
Motohara, Institute of Astronomy, University of Tokyo; Y. Kobayashi,
National Astronomical Observatory of Japan; M. Suganuma and H.
Tomita, Department of Astronomy, University of Tokyo; and B. A.
Peterson, Australian National University, report the following
magnitudes (uncertainty 0.1-0.2 mag, optical magnitudes on Johnson-
Cousins system) obtained with an optical and near-infrared camera
(MIP) at the Cassegrain focus of the MAGNUM 2-m telescope at
Haleakala Observatory, Maui:  Feb. 2.408 UT, B = 13.34; 2.420, J =
12.54; 2.431, V = 12.82; 2.438, R = 12.79; 2.445, K = 12.31; 2.450,
U = 13.51; 4.396, B = 13.15; 4.400, J = 12.27; 4.405, V = 12.54;
4.413, U = 13.23; 4.417, K = 11.94; 4.422, R = 12.51.


SUPERNOVA 2002H IN MCG -02-35-11
     T. Matheson, S. Jha, P. Challis, and R. Kirshner, Harvard-
Smithsonian Center for Astrophysics, report that a spectrum (range
370-750 nm) of SN 2002H (cf. IAUC 7798, 7815), obtained by M.
Calkins on Jan. 22.54 UT with the Mt. Hopkins 1.5-m telescope (+
FAST spectrograph), shows it to be a type-Ia supernova, about three
weeks past maximum.
