* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1253.

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), Seiichi Yoshida, and other contributors.

* Special Notes

It was mis-classified as SR type at the discovery. But Tsutomu Fujiwara revealed that it is not reddish as V-Rc = 0.0 mag. It seems to be an Algol-type eclipsing variable.
