SUNGRAZING COMETS
     Further to IAUC 7567, D. Hammer reports his measurements for
several additional Kreutz sungrazing comets from SOHO C2
coronagraph data.  Comets C/2000 H5 and C/2000 X8 were found by D.
Biesecker, and the remaining comets were found at the SOHO website
by M. Oates.  The reduced observations and orbital elements by B. G.
Marsden appear on the MPECs cited below.
