* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered a new variable star MisV1278.

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

Patrick Wils researched the NSVS data and commented that MisV1278 has a small range 12.6-12.8, and a possible frequency of 2.787 cycles/day, or an alias thereof, but because of the small range, it is doubtful.

Kazuhiro Nakajima's observations revealed it is an Algol-type (EA) eclipsing variable with unfiltered CCD variations of 13.35 mag at maximum, 13.82 mag at primary minimum, 13.77 mag at secondary minimum, and period of 1.1205 days (IBVS 5700).
