     J. Mueller reports her discovery of an apparent supernova (mag
about 16) on a near-infrared IVN plate taken on May 31 UT by K.
Rykoski with the 1.2-m Oschin Schmidt telescope in the course of
the second Palomar Sky Survey.  SN 2000cm is located at R.A. =
12h12m59s.1, Decl. = +7o17'53" (equinox 2000.0), which is 9" west
and 6" north of the center of the apparent host galaxy.  The new
object also appears on other Sky Survey IVN plates taken on June 1
and 3 by Rykoski, but there no object present at this position on
the Digitized Sky Survey or on a red second Sky Survey plate taken
on 1996 Apr. 26 by Mueller.

SUPERNOVA 2000cn IN UGC 11064
     M. Papenkova and W. D. Li, University of California at
Berkeley, on behalf of the Lick Observatory Supernova Search (cf.
IAUC 6627, 7126), report the discovery with the 0.8-m Katzman
Automatic Imaging Telescope of an apparent supernova on unfiltered
images taken on June 2.5 (mag about 17.4) and 3.4 UT (mag about
16.9).  SN 2000cn is located at R.A. = 17h57m40s.42, Decl. =
+27o49'58".1 (equinox 2000.0), which is 7".2 west and 7".2 south of
the nucleus of UGC 11604.  An unfiltered image of the field taken
on May 29.5 showed nothing at the position of the new object
(limiting mag about 19.0).

SUPERNOVA 2000co IN MCG +7-33-17
     T. Puckett, Mountain Town, GA, reports the discovery of an
apparent supernova (mag 19.2) on an unfiltered CCD frame (limiting
mag 20.5) taken with the Puckett Observatory 0.60-m automated
supernova patrol telescope on June 2.26 UT.  SN 2000co is located
at R.A. = 15h57m24s.59, Decl. = +41o54'02".0 (equinox 2000.0),
which is 4".1 east and 9".0 south of the center of MCG +7-33-17.
The new object was also present on an unfiltered CCD frame taken on
June 3.11, but it does not appear on Palomar Sky Survey images
taken on 1988 May 15 (limiting mag about 21.5) or 1991 Apr. 10
(limiting mag about 21.5).

     Visual magnitude estimates:  May 8.014 UT, 9.0 (A. Baransky,
Kiev, Ukraine); 16.736, 9.8 (A. Pearce, Nedlands, W. Australia);
21.750, 10.5 (S. Yoshida, Ibaraki, Japan); June 1.842, 10.8
