AAVSO NEWSFLASH SPECIAL NOTICE (September 19, 2003)
Subject: 1803-27 NOVA SAGITTARII 2003 NUMBER 2
We have been informed by the IAU Central Bureau for Astronomical Telegrams
(IAU Circular 8204) of the discovery of a nova in Sagittarius by Nicholas
Brown, Quinns Rocks, W. Australia, at magnitude 9.2 on T-Max films taken on
September 17.52 UT using a 135-mm f/2 camera lens. Brown estimated it at
visual magnitude 8.8 on Sep. 18.43; nothing was visible to magnitude 11.0 on
his films from Sep. 14.55. H. Yamaoka, Kyushu University, Japan, reported the
nova at CCDV magnitude 10.7 on an ASAS-3 frame taken Sep. 16.07 UT (image
merged with those of two neighboring stars). W. Liller, Vina del Mar, Chile,
reported nothing visible to magnitude 11.5 on a red film taken on Sep.
13.12 UT.
Spectra by D. West, Mulvane, KS (Sep. 19.0847), and by Liller (Sep. 19.104)
showed H-alpha in emission, and spectra by R. Guch, E. Polomski, C.E.
Woodward, University of Minnesota; R.M. Wagner, LBT Observatory; and S.
Starrfield, Arizona State University (Sep. 19.10), confirm the object as a
Fe-II-class nova early in decline.
A precise position of the nova provided by West from CCDV images obtained by
him on Sep. 19.085 UT is given as:
R.A. = 18h 10m 10.42s, Decl. = -27o 45' 35.2" (equinox 2000.0)
Brown noted the nova as being close to GSC 6851:1342 (listed as magnitude 11.9).
