SUPERNOVAE 2003ew, 2003ex, 2003ey, AND 2003ez
     Further to IAUC 8140, several additional apparent supernovae
have been reported by L. G. Strolger et al. (2003ew), by W. M.
Wood-Vasey et al. (2003ex, 2003ey) and by M. Papenkova and W. Li
(2003ez).

NOVA IN NGC 6822
     Papenkova and Li also report the LOTOSS discovery of an
apparent nova in NGC 6822 on unfiltered KAIT images taken on May
28.4 (mag about 19.0) and June 3.4 UT (mag about 19.2).  The new
object is located at R.A. = 19h45m04s.18, Decl. = -14o45'46".5
(equinox 2000.0), which is 0".8 west and 2".7 north of a foreground
star of mag about 18.5.  A KAIT image taken on 2002 Sept. 4.3
showed nothing at this position (limiting mag about 20.0).


SUPERNOVA 2003ep IN NGC 7053
     T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian
Center for Astrophysics, report that a spectrum (range 370-750 nm)
of SN 2003ep (cf. IAUC 8140), obtained by P. Berlind on June 4.46
UT with the F. L. Whipple Observatory 1.5-m telescope (+ FAST
spectrograph), shows it to be a reddened type-Ia supernova, 3-4
weeks past maximum.  There is a relatively strong (equivalent width
about 0.15 nm) Na I D absorption line at the velocity of the host
galaxy.
