* Discovery Information

Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV0988.

It was picked up by Yoshida from the candidates of new variable stars detected by the PIXY system from images taken by Ohkura comparing with images taken by Kadota. Kadota and Yoshida judged it as a real variable star.

The identification with the 2MASS data is by Taichi Kato.

XX Sge is 2.3 arcmin from MisV0988. XX Sge is an eclipsing binary, detected at 14.0 mag on these images. MisV0988 is thus a new variable star.

* Special Notes

Tsutomu Fujiwara's observations revealed that MisV0988 is a Mira-type variable with a period of 430 days (light curve).
