Copernicus Observatory), the simultaneous observations are successfully ongoing. The amplitude of periodic variation looks larger (full amplitude ~0.07mag) and the amplitude of short time fluctuations looks smaller seen in our recent light curve. The intensive campaign including HST, RXTE, and USA is now ongoing. We will have a clear sky tonight and over four hours observation is expected.
