[vsnet-alert 7088] Possible nova in Oph (HadV105)

[Taichi Kato <tkato@kusastro.kyoto-u.ac.jp>]

Possible nova in Oph (HadV105)

   Katsumi Haseda (Aichi, Japan) reports the discovery of a possible nova
in Oph (HadV105).

   Haseda provides the following semi-accurate coordinates (possible
uncertainty 10"):

   17h 37m 34.5s, -16o 23' 22"  (J2000.0)

   There is no known or suspected variable, no bright (brighter than 14.5)
DSS star and no bright 2MASS source at the reported position.  No known
(bright) minor planet is found at this position.

   The object is thus very likely a nova or a some sort of exploding object.
Confirmatory observations, accurate astrometry, photometry and spectroscopy
are most urgently requested.
