COMET 2002 K1
     K. Lawrence, E. Helin, and S. Pravdo, Jet Propulsion
Laboratory, report the discovery of a comet with a tail about 8"
long toward the southwest (and m_2 = 19.4-19.6) on images taken
with the 1.2-m NEAT telescope at Haleakala.  Confirming CCD images
by E. S. Barker at McDonald Observatory (0.76-m reflector) show a
15" tail toward the southwest.

SUPERNOVA 2002cw IN NGC 6700
     M. Papenkova and W. D. Li, University of California at
Berkeley, report the LOTOSS (cf. IAUC 7514) discovery of an
apparent supernova on an unfiltered CCD image taken with the 0.8-m
Katzman Automatic Imaging Telescope (KAIT) on May 16.5 UT (mag
about 18.7).  The new object was confirmed on an earlier image
taken on May 4.5 at about the same brightness.  SN 2002cw is
located at R.A. = 18h46m02s.40, Decl. = +32o17'03".2 (equinox
2000.0), which is 25".0 west and 16".0 north of the nucleus of NGC
6700.  A KAIT image taken on 2001 Oct. 1.2 showed nothing at this
position (limiting mag about 19.5).


SUPERNOVA 2002cx IN ANONYMOUS GALAXY
     W. M. Wood-Vasey, G. Aldering, and P. Nugent, Lawrence
Berkeley National Laboratory, report the discovery of an apparent
supernova (mag 18.9) on unfiltered CCD images taken with the Oschin
1.2-m telescope at Palomar on May 12.21 UT as part of a joint
collaboration with E. F. Helin, S. Pravdo, M. Hicks, and K.
Lawrence (Near-Earth Asteroid Tracking project).  SN 2002cx is
located at R.A. = 13h13m49s.72, Decl. = +6 57'31".9 (equinox
J2000.0), which is 18" south and 11" east of the center of its
apparent host galaxy.  The new object was confirmed (mag 18.1) on
subsequent images taken on May 16.2.  No object is apparent on
images from Apr. 23 and May 6 (limiting mag 20).
