Observing Notes - 07/18/2017 Observatory: WIRO Observers : David PeQueen, Cristilyn Cortez, Aylin McGough, Jacob McLane Notes: - Too cloudy to take evening flats. - Original target at high air mass (~2.77) at about 10:00 MT, so decided to take out of transit data on TrES-3 b in g' and r' filters. Data seemed to be highly affected by either high, thin atmospheric clouds or general haze. - Switched to original target of HAT-P-8 b at about 12:15 MT. Taking science images in g' r' z' and i'. - Lot of haze / partial cloud cover much of the night. - Took 40 biases.
