* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1097.

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 (the United Kingdom), and Seiichi Yoshida.

* Special Notes

Ondrej Pejcha revealed it is a W UMa-type (EW) eclipsing variable. It is probably a blue one (EW/KE type), the minority among them.

Kazuhiro Nakajima's observations revealed the unfiltered CCD variations between 13.04 and 13.74 mag, and period of 0.4688 days (IBVS 5600).

Times of minima observed by Ondrej Pejcha are published in the IBVS paper (IBVS 5645).
