Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and
Ken-ichi Kadota, MISAO Project, discovered a new variable star
MisV1181.

It was picked up by Seiichi Yoshida from the candidates of new
variable stars detected by the PIXY system 2 from images taken by
Nobuo Ohkura, and confirmed by Ken-ichi Kadota. 

The identification is researched by Taichi Kato (Kyoto University),
John Greaves, and Seiichi Yoshida.

The magnitude are measured automatically by the PIXY system 2, except
for the images taken by Toshikazu Muramatsu on Nov. 25, 2002.

John Greaves pointed out that this is a possible cataclysmic variable.
We reported this discovery to IAUC as a possible nova or new transient
object in 2001.
