* Discovery Information

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.
