SUPERNOVA 2001ck IN UGC 9425
     W. D. Li, University of California at Berkeley, reports the
discovery by LOTOSS (cf. IAUC 7514) of an apparent supernova in
unfiltered images taken with the Katzman Automatic Imaging
Telescope (KAIT) on June 3.3 (mag about 17.2) and 4.3 UT (mag about
16.8).  The new object is located at R.A. = 14h37m50s.08, Decl. =
+30o29'02".2 (equinox 2000.0), which is 5".8 west and 3".0 north of
the northern nucleus of UGC 9425.  A KAIT image taken on May 24.3
showed nothing at this position (limiting mag about 18.5).


SUPERNOVA 2001cl IN NGC 7260
     Li also reports the LOTOSS discovery by M. Papenkova of
another apparent supernova (mag about 17.2) in unfiltered images
taken with the KAIT on June 4.5 and 5.4 UT.  The new object is
located at R.A. = 22h22m37s.52, Decl. = -4 07'30".8 (equinox
2000.0), which is 15".5 east and 16".0 south of the nucleus of NGC
7260.  A KAIT image of the same field taken on 2000 Dec. 5.2 showed
nothing at this position (limiting mag about 19.0).


SUPERNOVA 2001cm IN NGC 5965
     X. J. Jiang and Y. L. Qiu, on behalf of Beijing Astronomical
Observatory supernova survey, report the discovery of an apparent
supernova found on unfiltered images taken on June 3.62 (mag about
17.5) and 5.72 UT (mag about 16.8).  SN 2001cm is located at R.A. =
15h34m06s.70, Decl. = +56o41'26".2 (equinox 2000.0), which is 36".2
east and 16".4 north of the nucleus of NGC 5965.  An image taken on
June 2.60 shows nothing at this position (limiting mag about 18.0).


COMETS C/2001 K6, C/2001 K7, AND C/2001 K8 (SOHO)
     Further to IAUC 7634, D. Hammer reports his measurements for
three additional Kreutz sungrazing comets found by M. Oates, K.
Cernis, and T. Scarmato on LASCO C2 coronagraph images posted at
the SOHO website.  The reduced astrometry and orbital elements by
B. G. Marsden appear on MPEC 2001-L09.

    Comet         2001 UT           R.A. (2000) Decl.
    C/2001 K6     May  23.368        4 01.8   +18 58
    C/2001 K7          23.493        4 02.0   +19 00
    C/2001 K8          29.504        4 25.2   +19 54
