Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV1013.
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.
Special Notes
Tsutomu Fujiwara's observations revealed that MisV1013 is a semi regular variable with a period of 157 days (light curve).
