* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima, Okayama, Japan, discovered new variable stars MisV1393 - MisV1404.

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. Their variations were confirmed by Yoshida, Ohkura and Youichirou Nakashima.

* Special Notes

The USNO-A2.0 color is B-R = -0.4 mag. The RGB composite image from DSS I, R and Bj images also suggests that MisV1396 is remarkably blue.

MisV1396 faded only once by the MISAO Project observations. It is almost constant the other days. The NSVS light curve shows MisV1396 is almost constant, or maybe it shows a small irregular variation.

But Arne Henden revealed it is not so blue, as the TASS color is (V-Ic) = 0.41, the Tycho color is (B-V) = 0.275, and the 2MASS color is J=10.704, H=10.662, K=10.592.
