The decline rate became faster on July 8 - 9 with 0.2mag/d, but still be at bright state as previously reported. Combining our data on July (1383 points), we performed preliminary period analysis. The fourie analysis yields the strongest peak at ~0.0725 d, but the power is weak. The other candidates of 0.022 d or its double are also seen. More time-series observations are needed.
