supernovae in unfiltered Katzman Automatic Imaging Telescope (KAIT)

SUNGRAZING COMETS
     Further to IAUC 7764, several additional comets have been
found on SOHO website images by S. Hoenig (C/2001 X4, X9), M. Meyer
(C/2001 X5, X6), M. Boschat (C/2001 X7, Y5), A. Mimeev (C/2001 X8),
and X. Zhou (C/2001 Y2, Y3, Y4).  Astrometry (measurements by D.
Hammer, reduction by B. G. Marsden) and orbital elements appear on
the MPECs cited below.  All but C/2001 X8 (q about 0.037 AU, i
about 72 deg) appear to be Kreutz sungrazers; all the comets were
visible in the C2 coronograph (C/2001 Y5, which was fairly bright
with a long tail, was also visible in C3).
