Dear colleagues, I found an interesting object MisV0015 = OGLE2-BUL-SC22-V383. The finding chart is: http://vsnet.aerith.net/misao/data/MisV/MisV0015.gif 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. It may be a low amplitude irregular long period variable. But, the light curve from the OGLE's observations: http://vsnet.aerith.net/misao/report/variable/MisV-OGLE2-BUL/MisV0015.gif looks similar to those of GCAS stars like: http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/gcvs/SCOdelta.html http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/gcvs/OPHchi.html GCAS is an eruptive irregular variable of the Gamma Cas type, rapidly rotating B III-IVe star with mass outflow from it equatorial zone (from GCVS variability types description). But the 2MASS J-Ks color of MisV0015 is so large as 1.303 mag. Can it be a GCAS star? Best regards, -- Seiichi Yoshida comet@aerith.net http://vsnet.aerith.net/
