An observation from the Metsähovi Observatory of the University of Helsinki about the overflow of the exoplanet TrES-2 b. The orange ticks in the image are single 30 s exposures, and the blue curve averages 5 consecutive exposures. The magnitude is calculated as the average of the two reference stars and normalized so that the average of the first 10 data points is 0.

In the CCD image, TrES-2 is the lowest star circled in red. The other two circled stars served as reference stars against which the brightness of the object was compared.
