* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV1073.

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 comparing with images taken by Ken-ichi Kadota, and confirmed by Ken-ichi Kadota.

The identification is researched by Taichi Kato (Kyoto University), John Greaves (the United Kingdom), and Seiichi Yoshida.

* Special Notes

John Greaves pointed out that there is an X-ray star 1RXS 200142.7+465727 about 1 arcmin south of MisV1073. But they are probably not the same because of the large distance.
