COMETS C/2000 H6, H7, J8, N4; C/2002 J3 (SOHO)
     Further to IAUC 7898, D. Hammer reports his measurements for
additional comets found by R. Kracht (2000 comets; C2 coronagraph)
and by K. Cernis (C/2002 J3; C3) in the SOHO archive.  The reduced
astrometry and orbital elements by B. G. Marsden appear on the
MPECs cited below.  Comets C/2000 H6, C/2000 H7, and C/2002 J3 are
members of the Kreutz group; the other two belong to the Meyer
group (cf. IAUC 7832).

COMET C/2002 J4 (NEAT)
     S. Pravdo, E. Helin, and K. Lawrence, Jet Propulsion
Laboratory, report the discovery by NEAT, on CCD images taken on
May 13.5 UT with the Palomar 1.2-m Schmidt telescope, of a comet
with nebulosity extending about 5" toward the southwest.  Following
posting on the NEO Confirmation Page, additional observations
obtained elsewhere on May 13.9 confirm the cometary nature:  P.
Kusnirak at Ondrejov (0.65-m reflector; m_1 = 18.3, faint 7" coma
slightly elongated to the southwest); M. Tichy and M. Kocer at Klet
(1.06-m KLENOT telescope; compact coma of diameter 16"); and L.
Kornos at Modra (0.6-m reflector; m_1 = 16.6, coma diameter about
15").  Additional observations made by LONEOS and LINEAR on May 4,
7, and 8 were then identified by the Minor Planet Center staff.

Astrometry and the following preliminary parabolic orbital elements
appear on MPEC 2002-J47:
