Dear colleagues,
I report new variable stars discovery in the course of the MISAO
Project (MisV1388 - MisV1392).
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.
Patrick Wils proposed the period of MisV1392 as 0.4970 days, but
Seiichi Yoshida investigated the NSVS data and found a period of
0.49695 days is better.
