Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1237.
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.
Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.34 mag at maximum, 13.94 mag at primary minimum, 13.90 mag at secondary minimum, and period of 7.5530 days (IBVS 5700).
Our second eccentric binary. The secondary minimum occurs at the phase of 0.484.
