1903+12 NOVA AQUILAE 1999
We have been informed by the Central Bureau for Astronomical Telegrams (IAU
Circular Number 7223) of a photographic discovery of a nova by A. Tago,
Tsuyama, Japan, at a magnitude of 8.8 on July 13.558 UT. Tago reports the
coordinates as R.A. = 19h07m40s, Decl. = +12o32'.2 (equinox 2000). A CCD
image taken by A. Nakamura, Kuma Kogen Astronomical Obervatory, Japan,
on July 14.513 UT places the position at R.A. = 19h07m36s.90, Decl. =
+12o31'26".2 (equinox 2000). The nova was confirmed spectroscopically by
K. Ayani and T. Kawabata, Bisei Astronomical Observatory, Okyama, Japan.
An AAVSO Alert Notice and chart(s) for observing this nova will be issued
tomorrow.
