COMET C/2002 T7 (LINEAR)
     Another object reported as asteroidal by the LINEAR survey has
been found to be cometary in appearance.  P. Birtwhistle, Great
Shefford, U.K., writes that CCD images taken on Oct. 28.0 UT show
the object to be slightly 'softer' than stars of similar brightness.
T. B. Spahr reports that Mt. Hopkins images taken on Oct. 29.4 show
the object to be very slightly diffuse, again with it being
slightly larger than the FWHM of nearby stars.

     Oct. 14.41856    6 03 49.91   +27 50 02.7   17.5

     The available astrometry (some giving the comet's magnitude as
bright as 16.5), including an Oct. 12 prediscovery observation, is
given on MPEC 2002-U43, together with the preliminary parabolic
orbital elements below.  It is possible that this comet could reach
naked-eye brightness around April--June 2004.

V4744 SAGITTARII = POSSIBLE NOVA IN SAGITTARIUS
     N. N. Samus, Institute of Astronomy, Moscow, informs us that
the designation V4744 Sgr has been given to this object (cf. IAUC
8001).
