| Photometric Detection of a TrES-3 exoplanet transit at Kobdilj Observatory (May. 18-19, 2007) |
| We report a photometric
confirmation of a TrES-3 exoplanet transit, performed by exoplanet
and variable star group (Teja Fabjan, Primož Kuk, Matej Mihelčič and
Nikolaj Štritof - all from Kobdilj Observatory). We successfully
observed the TrES-3 exoplanet candidate transit on May 18-19, 2007
with 0.25-m LX200 telescope, working at f/3.9, StarlightXpress MX716
CCD and V filter. A total of 120 exposures were secured, each
lasting 80 seconds. Comparison stars were GSC 3089 883 (C) and GSC
3089 1137 (C1). The weather conditions were very good throughout the
observing session.
The TrES-3 object is located at R.A. = 17h 52m 07s, Decl. = +37° 32' 46" (equinox 2000.0). Complete observations are available here. In case you intend to use our data, please credit it to Kobdilj Observatory, Slovenia. |

| While checking for the suitable comparison stars in the TrES-3 field, we discovered that GSC 3089 1027 is a variable star. Our data analysis show it is most probably of Delta Scuti type.
