COMET P/2002 T6 (NEAT-LINEAR)
     An object reported as asteroidal independently by the NEAT and
LINEAR surveys, and later placed on the NEOCP, has been found
cometary in appearance.  P. Birtwhistle, Great Shefford, U.K.,
reports that CCD images taken with a 0.3-m reflector on Oct. 27.9
UT show two faint, thin, straight tails in p.a. 107 deg (36" long)
and 310 deg (39" long) and a nuclear condensation with diameter
about 8".  T. B. Spahr reports that 5-min exposures taken with the
Mt. Hopkins 1.2-m reflector on Oct. 29.2 show a small coma of
diameter about 6" and an extremely faint tail about 10" long in
p.a. 330 deg.

SUPERNOVA 2002he IN UGC 4322
     Further to IAUC 7999, J. Graham and W. D. Li report the LOTOSS
discovery of an apparent supernova on unfiltered KAIT CCD images
taken on Oct. 28.5 (mag about 17.5) and 29.5 UT (mag about 17.1).
SN 2002he is located at R.A. = 8h19m58s.83, Decl. = +62o49'13".2
(equinox 2000.0), which is 19".7 west and 37".3 south of the
nucleus of UGC 4322.  A KAIT image taken on Oct. 22.5 showed
nothing at this position (limiting mag about 19.0).


SUPERNOVAE 2002hb AND 2002hd
     M. Hamuy, Carnegie Observatories, reports that a spectrum
(range 360-900 nm) of SN 2002hb (cf. IAUC 7999), obtained on Oct.
29.13 UT with the Las Campanas Baade 6.5-m telescope (+ LDSS2),
shows it to be a type-Ia supernova, 3-4 weeks past maximum light,
at a redshift of approximately 0.09.  A spectrum of SN 2002hd,
obtained with the same instrument on Oct. 29.35, reveals it to be a
type-Ia supernova, about 5 days past maximum light, at a redshift
of approximately 0.035.
