Nova Scuti 03 page
A Rainbow Optics transmission grating placed immediately before the CCD produces a second image or spectrogram dispersed to one side of the star image according to wavelength from 3700A-9500A with a resolution ~50A. This raw image screen capture shows a bright point of Ha [6563A] that is always present in a nova at outburst. The intensity profile through the spectrogram, via SX camera controlling software, confirms this. The intensity profile is software enhanced to reveal more detail.

Aug 31 : The Astronomer webpage quotes: Possible nova in Scutum. IAUC 8190
and VSNET report the discovery of a possible nova by Hideo Nishimura (Kakegawa,
Shizuoka-ken, Japan) on T-Max films taken on Aug. 28.58 (mag 8.5) and 29.436
UT (mag about 8.4) with a Pentax 200-mm f/4.0 lens. This object is well-placed
for observation from the UK being almost due south as the sky gets dark.
Position R.A. 18h 49m 37.7s
Decl. -9o 33' 52.7" (J2000.0).
2003 Aug 31 @ 20:30UT: First spectrum to confirm this nova? These continuing WPO spectrograms of Nova Sct 03 including perhaps the first spectrogram to confirm the nova by its characteristic Ha emission. However the nova did not initially appear to be a classic nova but closely resembled the spectrum of V838 Mon [peculiar Nova Mon 02] for 2002 Feb 3/4 below shown overlaid onto Nova Sct 03. The spectrum of Sept 1/3/4 shows the nova rapidly evolving into a more classic nova spectrum with many emission lines. Sept 6/7 show little change.

838 Mon comes good!
