Seiichi Yoshida, MISAO Project; and KenIchi 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.

The magnitude are measured automatically by the PIXY system. Image
observers' names are noted after "Mis".

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.
