[vsnet-alert 7830] Bright nova candidate in Scutum



Bright nova candidate in Scutum

Dear Colleagues,

   I have personally received a notification of the likely nova discovery
in Scutum via H. Yamaoka.  Although I have been asked not to relay the
discovery alert to the public, I relay the following information by my own
judgement because of the very likely nova nature of the object and the
presence of an apparently bright quiescent counterpart.
If the object is indeed a classical nova, it may further brighten to
a naked-eye object or a easy binocular object.

   Use "SCTnova2003" temporary name in VSNET reporting.

ASAS-3 position
R.A. = 18:49:37.7
Decl. = -9:33:52.7 (J2000.0).

  Tentative quiescent identification:

18:49:37.684 -09:33:53.76 r=16.4 b=17.2 USNO-A2.0
18:49:37.663 -09:33:53.74 r=15.71       GSC-2.2
18:49:37.67  -09:33:53.9  r=15.87 b=17.47 USNO-B1.0
18:49:37.70  -09:33:54.1  J=14.318 H=14.007 K=13.818  2MASS
18:49:37.71  -09:33:53.9  DENIS-2

ASAS-3 data: 
Aug. 24.105   V>14.0
Aug. 26.096   V=10.15
Aug. 28.096   V=8.94

   The discovery date was on August 28.577 UT (mag 8.5, T-Max).  Further
details of the discovery is expected to be soon announced in CBET or IAUC.

Regards,
Taichi Kato
