Transit light curve of transiting planet TrES-2 obtained on 13 Oct 2007 with the GSH CTK CCD camera. We plot brightness of star (as relative flux) versus observing time (as Julian Date), the transit started at time 0.48d and ended at 0.56d, i.e. lasted 0.08d (almost 2 hours), the transit depth is about 1.5% only.
