     The Smithsonian Astrophysical Observatory announces that the
2003 Edgar Wilson Award for the discovery of comets (cf. IAUC 6936,
7926) is being divided among the following five individuals:
Sebastian Florian Hoenig, Dossenheim, Germany, for C/2002 O4; Tetuo
Kudo, Kikuchi, Kumamoto, Japan, and Shigehisa Fujikawa, Mitoyo,
Kagawa, Japan, for C/2002 X5; Charles Wilson Juels, Fountain Hills,
AZ, U.S.A., and Paulo Renato Centeno Holvorcem, Campinas, Brazil,
for C/2002 Y1.

SUPERNOVA 2003gk IN NGC 7460
     Further to IAUC 8161, J. Graham and W. Li report the LOTOSS
discovery of an apparent supernova on unfiltered KAIT images taken
on July 1.5 (mag about 17.1) and July 2.5 UT (mag about 17.2).  SN
2003gk is located at R.A. = 23h01m42s.99, Decl. = +2o16'08".7
(equinox 2000.0), which is 1".6 east and 19".2 north of the nucleus
of NGC 7460.  A KAIT image taken on 2002 Dec. 3.2 showed nothing at
this position (limiting mag about 19.0).

     J. Beish, Lake Placid, FL (0.41-m reflector, visual); and D.
C. Parker, Coral Gables, FL (0.41-m reflector, CCD), report that a
dust cloud has formed and brightened during July 1 and 2 in the
Iapygia-Ionium-Hellas region centered at longitude approximately
294 deg west and latitude approximately 25 deg south.

     Z. Abraham and T. P. Dominici, Sao Paulo University and Sao
Paulo State Research Foundation, report that radio measurements at
7 mm, made at the Itapetinga Radio Observatory, show that the flux
density decreased from 3 Jy on May 22 to 1.5 Jy on June 20,
remaining constant since then.  A. Damineli, N. Leister, and R.
Levenhagen report that spectroscopy, obtained at the Pico dos Dias
Observatory, shows the complete disappearance of the [Ne III]
386.8-nm spectral line on June 23.  Both results indicate that eta
Car has entered the deepest phase of the 2003.5 event, as predicted
by Damineli et al. (2000, Ap.J. 528, L101).
