I managed to cover this star for 3.4 hours, remotely using the 17" robotic unit
part of the Virtual Telescope facility in Italy. Real time data reduction was
Data are of good quality, especially at the beginning of the run, later haze and
full Moon increased the scattering. I used 10 seconds of integration
(unfiltered), getting 700 data points. The star was at mag 13.8 (unfiltered)
The star shows an evident modulation, likely double peaked (the second peak is
of small amplitude), 0.1 mag large.
A period search provided a candidate of P=0.82(3) hours.
Data will be send to Kyoto for analysis.
