Exoplanet TrES-2b is an “old friend” for Taurus Hill Observatory’s research team. Last time the light curve of the TrES-2b was measured in February 2008. This time the reserach team managed to measure the whole light curve. There seems to be a minor rise in the first half of the light curve and might be an indicator of star spot. The star itself (GSC 3549-2811) is very much like the Sun. The star is located in the near of the Cygnus.

The mesurements were made with the photometric R-filter and the comparison stars were GSC 3549-2716 (C1), GSC 3549-2704 (C2), GSC 3549-2776 (C3), GSC 3550-1224 (C4) and GSC 3549-2837 (C5).

At the moment of the measurements the object was about 50 degrees high in the east. The sky was little foggy and the temperature was about 0 celsius degrees.
