* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

* Special Notes

John Greaves identified with OGLE2-BUL-SC22-V383.

The variation range from OGLE's I-band observations is small as 11.838 - 11.933 mag, although the range from MISAO's unfiltered CCD observations is large as 12.8 - 14.3 mag.

The OGLE-II light curve looks similar to those of GCAS stars. A GCAS star should be B type, however, the 2MASS J-Ks color of MisV0015 is so large as 1.303 mag.

Further researches revealed that identification of MisV0015 with USNO-1.0 0525.24950305 was wrong. There is no identification in USNO-A1.0 at the corrected position measured from Ken-ichi Kadota's images. At the same time, identification with OGLE2-BUL-SC22-V383 was also wrong. Based on the corrected position, MisV0015 is identified with a Mira type variable with a period of 217 days, OGLE2-BUL-SC22-V384.
