COMETS C/2002 J6, C/2002 J7, C/2002 K3 (SOHO)
     Further to IAUC 7899, D. Hammer reports his measurements for
additional Kreutz sungrazing comets found by X. Leprette (C/2002
J6), R. Matson (C/2002 J7), and R. Kracht (C/2002 K3) on SOHO
website C2 images.  The reduced observations and orbital elements
by B. G. Marsden are included on MPEC 2002-K48.

COMET 2002 K4
     S. Pravdo, E. Helin, and K. Lawrence, Jet Propulsion
