SUPERNOVA 2001cy IN UGC 11927
     M. Ganeshalingam, M. Modjaz, and W. D. Li, University of
California at Berkeley, report the discovery by LOTOSS (cf. IAUC
7514) of an apparent supernova in unfiltered images taken with the
Katzman Automatic Imaging Telescope (KAIT) on June 30.5 (mag about
16.3) and July 1.4 UT (mag about 16.2).  The new object is located
at R.A. = 22h09m27s.76, Decl. = +40o59'16".5 (equinox 2000.0),
which is 3".6 east and 6".1 south of the nucleus of UGC 11927.  A
KAIT image taken on June 19.5 showed nothing at this position
(limiting mag about 19.5).

COMETS C/2001 M7, C/2001 M8, C/2001 M9 (SOHO)
     Further to IAUC 7650, D. Biesecker and D. Hammer report
measurements of three additional Kreutz sungrazing comets found by
K. Cernis, X. Leprette, and M. Oates on SOHO website images.
C/2001 M7 and C/2001 M8 were visible in both the C2 and C3
instruments, while C/2001 M9 was visible only in C2 images.  The
reduced astrometry and orbital elements by B. G. Marsden appear on
the MPECs cited below.

COMET C/2001 M10 (NEAT)
     M. D. Hicks, Jet Propulsion Laboratory, reports that this
comet shows a diffuse coma of diameter about 5" and a faint tail
about 7" long in p.a. 240 deg in a 10-min R-band CCD exposure
obtained on June 30.3 UT with the 0.61-m reflector at Table
Mountain (observers D. Esqueda, Hicks, and T. Ha).  Hicks' name
also should be added to the list of NEAT team members on IAUC 7654.
