> Now I am observing V503 Cyg (October 9 16:00 UT), > the object is not visible on our screen. > Although the sky condition is not good, I can see ~15mag near stars. After redution, the PSF photometry of these images yields the magnitude to be 15.07. During our 2-hour run, no periodic modulation can be seen. It seems to experience a normal outburst and return to the quiescence. Regards, Makoto Uemura
