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.
