Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV1021.

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.
