COMET P/2004 CB (LINEAR)
     An apparently asteroidal object discovered by the LINEAR
project (discovery observation below from MPEC 2004-C16 and MPS
98921) has been found to show a narrow 1'.1 tail in p.a. 274 deg
(slightly expanding toward the end) on CCD images obtained by R. H.
McNaught with the 1.0-m f/8 reflector at Siding Spring on Mar. 30.8
UT.  Following a request by the Central Bureau, M. Kocer reports
that CCD frames taken at Klet on Mar. 31.145 also show a narrow
tail about 90" long in p.a. approximately 280 deg.

ephemeris appear on MPEC 2004-F96.

SUPERNOVAE 2004ba AND 2004bb
     D. Norman, Cerro Tololo Interamerican Observatory (CTIO); G.
Squires, Space Infrared Telescope Facility, California Institute of
Technology; J. Kubo, Brown University; and A. Becker, University of
Washington, on behalf of the 'Deep Lens Survey' team, report the
detection of three possible supernovae in R and (subsequent) V-band
images taken with the CTIO 4-m reflector (+ MOSAIC imager).  The
two objects with apparent hosts are tabulated below.
