* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1223.

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

Patrick Wils and John Greaves revealed that it is a Cepheid variable with a period of 8.2 days from the NSVS data (IBVS 5512).

Based on the V-band survey from Oct. 25 to Dec. 7 in 2003, and Rc-band survey from Sept. 30 to Dec. 14 in 2004 by Nobuo Ohkura, the light curve is obtained and it was confirmed to be a Cepheid variable with a period of 8.2 days. The magnitude ranges are revealed to be 11.99-12.51 mag in V-band, and 11.20-11.80 mag in Rc-band.

Toshihito Ishida commented that this star belongs to a group named bump Cepheid, a Cepheid variable with a bump in its light curve.
