* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1317.

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.

* Special Notes

Kazuhiro Nakajima's observations revealed it is a beta Lyr-type (EB) eclipsing variable with unfiltered CCD variations of 11.90 mag at maximum, 12.70 mag at primary minimum, 12.12 mag at secondary minimum, and period of 1.28482 days (IBVS 5700).

Atsushi Miyashita caught the primary eclipse on 2008 Feb. 21 and confirmed that the ephemeris error is less than 5 minutes (light curve).
