SUPERNOVA 1999cd IN NGC 3646
M. Papenkova and W. D. Li, University of California at Berkeley, on
behalf of the Lick Observatory Supernova Search, report their
discovery with the 0.8-m Katzman Automatic Imaging Telescope (KAIT)
of an apparent supernova in NGC 3646.  The new object was
discovered on unfiltered images taken on May 14.224 and 14.279 UT
(mag about 17.9) and was confirmed on images taken on May 15.175
(mag about 17.6).  SN 1999cd is located at
R.A. = 11h21m42s.89, Decl. = +20o09'24".1 (2000), which is about
3".7 west and 46".4 south of the galaxy nucleus.          IAUC 7169

COMET C/1999 J4 (LINEAR)
An asteroidal object reported by LINEAR on May 15.3 UT (mag
18.2-18.8) with unusual motion was noted on The NEO Confirmation
Page, and it has subsequently been reported to be cometary in
appearance by several observers.

SUPERNOVA 1999ce IN ANONYMOUS GALAXY
M. Papenkova also report their discovery of an apparent supernova
on an unfiltered image taken on May 16.2 UT (mag about 18.3) with
the 0.8-m Katzman Automatic Imaging Telescope (KAIT), the object
being confirmed on an earlier image taken on May 10.2 (mag about
18.8).  SN 1999ce is located at
R.A. = 11h28m51s.57, Decl. = +57o08'04".0 (2000), which is about
1".5 southeast of the nucleus of the host galaxy.

     May  19.36625   20 48 11.34   - 7 56 29.5   18.1
The following very preliminary parabolic orbital elements are
by B. G. Marsden:
     T = 1999 Oct. 30.589 TT          Peri. =  28.089
                                      Node  = 300.677   2000.0

COMET C/1999 K3 (LINEAR)
M. Elowitz, Lincoln Laboratory, Massachusetts Institute of
Technology, reports the discovery of an apparently cometary object
in LINEAR data, as follows:
