Discovery Information
Seiichi Yoshida, MISAO Project; Nobuo Ohkura, Okayama, Japan; and Ken-ichi Kadota, Ageo, Saitama, Japan, discovered a new variable star MisV0884.
It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ohkura comparing with images taken by Kadota, then confirmed by Yoshida.
Special Notes
When it was bright as 9.3 mag in the MISAO Project observations, Guy M Hurst and Mike Collins reported that MisV0884 was too faint, fainter than 11 mag. Hurst's observations are unfiltered CCD, as same as the MISAO observations.
Masayuki Suzuki's observations revealed that it is bright only in infrared and very faint even in Rc-band, as 10.6 mag (Ic), 15.0 mag (Rc) and fainter than 16.8 mag (V).
