COMETS C/2002 S8, S9, S10, S11, T2, T3 (SOHO)
     Further to IAUC 7986, D. Hammer reports additional comets
found on SOHO website C2 images by D. Evans (C/2002 S8), S. Hoenig
(S9), M. Boschat (S10), T. Scarmato (S11), X. Leprette (T2), and M.
Oates (T3).  All were also observed in the C3 coronagraph except
for C/2002 T2, and all were Kreutz sungrazers except C/2002 S11
(Kracht group) and S/2002 T2 (Meyer group).  The reduced astrometry
and orbital elements by B. G. Marsden appear on MPEC 2002-T75.

COMET P/2002 T4 (NEAT)
     K. Lawrence, S. Pravdo, and E. Helin, Jet Propulsion
Laboratory, report the discovery on Oct. 11.22 UT of a comet (with
a nuclear condensation of diameter about 4" and a tail about 20"
long toward the south-southwest) on NEAT images taken at Palomar.
M. Hicks reports that images taken by J. Young at Table Mountain on
Oct. 12.3 (through cirrus clouds) show a diffuse coma and a faint
5" tail to the southwest.  D. Balam, University of Victoria,
reports that images taken by J. Clem with the 1.82-m Plaskett
telescope (also on Oct. 12.3) also show the object to be cometary
in appearance (3 pixels, or 3".3, larger than nearby stars).

The available astrometry (including prediscovery LINEAR
observations from Oct. 4 and 9), the following elliptical orbital
elements, and an ephemeris appear on MPEC 2002-T76.
