[vsnet-chat 7346] New variable star MisV1376

[Seiichi Yoshida]

Dear colleagues,

I report a new variable star discovery in the course of the MISAO
Project (MisV1376).

Seiichi Yoshida, MISAO Project; Nobuo Ohkura and Youichirou Nakashima,
Okayama, Japan; and Ken-ichi Kadota, MISAO Project, discovered new
variable star MisV1376.

It was 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.

The variation on the Nobuo Ohkura and Youichirou Nakashima's images
are somewhat doubtful. However, Ken-ichi Kadota investigated the DSS
images, and we concluded that it is a real variable.

The DSS images revealed that two faint stars are blending on the Nobuo
Ohkura and Youichirou Nakashima's images. The northern counterpart is
clearly visible on the DSS Bj-band image in 1989, however, not visible
on the B-band images in 1952 and 1954. It looks bright on the DSS
R-band and I-band images. 

The DSS images between 1989 and 1993, and the USNO-B1.0 data suggest
no proper motion. So we concluded that MisV1376 is the northern
counterpart, and is a red variable.
