POSSIBLE NOVA IN SCUTUM
     C. Boeche and U. Munari, Asiago Observatory, report on
spectroscopy (range 372-491 nm; disperson 0.23 nm/pixel) of the
possible nova reported on IAUC 8190, using the Asiago 1.22-m
telescope on Aug. 31.97 UT under somewhat-cloudy conditions:  "The
Balmer series is weakly in emission down to H_epsilon, and the line
width is not appreciably larger than the instrumental profile (300
km/s).  The Balmer-line profiles show a weak absorption component
blueshifted by 500 km/s and a second emission peak redshifted by 650
km/s with respect to the main emission line.  The well-developed
absorption spectrum closely match that of a normal F2 supergiant,
with normal intensity for s-element lines of Ba II (455.4 nm) and
Sr II (407.8, 421.6 nm).  A definitive classification with
classical novae must await future spectroscopic and photometric
development."
     W. Liller, Vina del Mar, Chile, reports that an objective-
prism spectrum taken on Aug. 31.093 UT shows a very narrow and weak
H_alpha emission with a peak approximately 0.47 times the intensity
of the nearby continuum; the FWHM appears to be no more than 300
km/s.  M. Fujii, Kurashiki, Okayama, Japan, reports that a low-
dispersion spectrum (range 390-850 nm; resolution about 1 nm),
obtained on Aug. 31.55 UT with a 0.28-m reflector, shows emission
lines of H_alpha (FWHM 700 km/s), H_beta, and Fe II (multiplets 42,
46, 49, 55, 74), with the Na I D absorption line.


SUPERNOVAE 2003hq, 2003hr, AND 2003hs
     Three additional apparent supernova have been reported from
unfiltered CCD images:  SN 2003hq by M. Armstrong (cf. IAUC 8176),
SN 2003hr by T. Boles (cf. IAUC 8185), and SN 2003hs by M.
Ganeshalingam and W. Li (LOTOSS/KAIT; cf. IAUC 8188).
