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.
Seiichi Yoshida researched the NSVS data, and revealed that MisV1385 is an RRAB-type variable with a period of 0.902 days.
Further observations are in progress by Kazuhiro Nakajima. The variations of MisV1385, MisV1386 and MisV1387 were also confirmed by Nakajima's photometry.
Patrick Wils commented that it has been found before by Wils P., Lloyd C., Bernhard K. (MNRAS 368, 1757), RRAB type variable with a period of 0.47414 days (not 0.902 days).
Light curve by the Northern Sky Variability Survey (NSVS) searched using SkyDOT.
