Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and
KenIchi Kadota, Ageo, Saitama, Japan, discovered a new variable star
MisV1139.

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 comparing with images taken by KenIchi Kadota, and
confirmed by KenIchi Kadota. 

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

The magnitude are measured automatically by the PIXY system 2.
