We performed high-speed photometry of this unidentified object on 18 Apr. The above light curve is an example of our 2-hour run. The time-resolution of the observation is 1 sec. We calculated the power spectrum using the light curve. No periodic variation was found. Short-term (2 sec - 100 sec) variations were weak. The light curve is apparently dominated by a white noise.
