Dear colleagues,
I report new variable stars discovery in the course of the MISAO
Project (MisV1380 - MisV1383).
Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima,
Okayama, Japan, discovered new variable stars MisV1380 - MisV1383.
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 (MisV1380, MisV1381), or taken by Nobuo Ohkura and
Youichirou Nakashima (MisV1382, MisV1383).
Seiichi Yoshida researched the NSVS data, confirmed the short periodic
variation, and revealed the type and period of these stars.
The USNO-A2.0 color, B-R = 2.5 mag, suggests MisV1383 is a reddish
cepheid.
