[vsnet-alert 17303] MisV1449 - possible new CV

[Seiichi Yoshida]

Dear colleagues,

We discovered a possible new cataclysmic variable MisV1449 from
Youichirou Nakashima's survey images with Canon 500-mm f/4.5 camera
lens + SBIG ST-8 in the course of the MISAO Project. It was bright at
15.3 mag on Apr. 23, and nothing found in our past images since 2000
by Nobuo Ohkura and Youichirou Nakashima.

Nothing is found on DSS or 2MASS images at this position. The Minor
Planet Checker says no known minor planets, brighter than V = 20.0,
were found in the 15.0-arcminute region around the position.

Red variable star V2193 Cyg = NSV 13178, R.A. 20h36m50s.88,
Decl. +32o23'33".7, 11.6-12.1 mag(p), exists near by this
position. But MisV1449 is another new object.

MisV1449
  R.A.  20h36m43s.45
  Decl. +32o23'11".9  (2000.0)
  Mag.  15.1-<16.4C
  Type  UG?
