Exoplanet TrES-2 b - 10.10.2018 at 20.15 - 10.10.2018 at 22.00 Kirkkonummi Observation number 78554

Visibility II / V

Teemu Willamo, Tuomas Salo, Ursa (Helsinki)

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.
