Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan, discovered new variable stars MisV1388 - MisV1392.
MisV1388 and MisV1389 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. Their variations were confirmed by Yoshida, Ohkura and Youichirou Nakashima.
MisV1390, MisV1391 and MisV1392 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 Yoshida.
Patrick Wils researched the NSVS data and revealed the periods of these new variable stars.
