Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered new variable stars MisV1384 - MisV1387.
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. Their variations were confirmed by Ohkura, Nakashima and Ken-ichi Kadota.
Further observations are in progress by Kazuhiro Nakajima. The variations of MisV1385, MisV1386 and MisV1387 were also confirmed by Nakajima's photometry.
Special Notes
Patrick Wils analyzed the NSVS data and revealed that MisV1387 is an EW type star with a period of 0.2628 days. Kazuhiro Nakajima revised the accuracy of the period as 0.263002 days.
