Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered new variable stars MisV1354 - MisV1364.
They were 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 Youichirou Nakashima, and confirmed by Ken-ichi Kadota.
It faded only once on 2007 Jan. 22 among 14 nights between 2000 and 2007. So it will be an Algol-type eclipsing variable, probably with a long period.
Special Notes
It was already found by Patrick Wils and solved by Sebastian Otero to be an EA eclipser with a period of 6.9092 days using the NSVS data, and published in IBVS 5681. Actually, it is not a new variable star of the MISAO Project.
