[vsnet-j 2961] Potentially bright apparent nova in Scutum

Potentially bright apparent nova in Scutum

　以下は vsnet-alert 等に流した情報です。状況によっては肉眼等級に達する
　可能性のある新星らしい天体で、しかも増光早期の可能性がありますので、
　独自の判断によって公開することにしました。発見者等の情報は CBET か IAUC
　で公表されると思われます。

＃ quiescence の同定が正しいかどうかは、精測位置で確認する必要があるでしょう。

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
