Discovery Information
Seiichi Yoshida, MISAO Project; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV0889.
It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Kadota, then confirmed by Yoshida.
OV Oph is 1.3 arcmin from MisV0889. No star brighter than 14.2 mag was detected at the cataloged position of OV Oph. However, OV Oph is recorded as an RR-type variable with a photographic magnitude range between 15.2 - 15.7 mag. Therefore, MisV0889 is thus a new variable star.
