SUPERNOVAE 2003bv, 2003bw, 2003bx, 2003by, 2003bz, 2003ca
     Six apparent supernovae have been reported from CCD images --
SN 2003bv by T. Boles (cf. IAUC 8089), SN 2003bw by B. Beutler and
W. Li (LOTOSS/KAIT; cf. IAUC 8092), and the rest by A. Becker and
the Deep Lens Survey Transient Team (cf. IAUC 7804, plus D. Loomba
and R. Wilcox) from the Cerro Tololo and Kitt Peak 4-m telescopes
(+ MOSAIC).  The magnitudes are unfiltered unless otherwise noted.

blue plates.


UNKNOWN VARIABLE
     Becker also reports the discovery of a variable object located
at R.A. = 9h22m38s.29, Decl. = +29o17'19".1, which is not near a
visible host galaxy.  Available magnitudes:  2001 Dec. 19 UT, R =
[25.5; 2003 Jan. 5, V = [25; Mar. 7.3, R = 23.4; 8.4, V = 23.1;
10.3, V = 22.9.


COMET 66P/DU TOIT
     J. V. Scotti has recovered this comet with the 1.8-m
Spacewatch II telescope at mag 20.3-20.7 on Mar. 10 and 11.  The
astrometry, revised orbital elements, and an ephemeris appear on
MPEC 2003-E57.  The indicated correction to the prediction on MPC
40670 is Delta(T) = -0.25 day.
