* 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.

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.

* Special Notes

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

Light curve by the Northern Sky Variability Survey (NSVS) searched using SkyDOT.
