Observing Notes - 07/28/2017 Observatory: WIRO Observers : Cristilyn Cortez, Aman Kar, Aylin McGough Notes: quality: 4/10 -no flats: tried to take evening flats, but couldn't due to cloud cover -window heater turned off at the beginning of the night, but we turned it back on due to the high humidity. We didn't see any residual evidence of the condensation issue from the previous night tonight. -found that filter u has a smudge in the upper left corner. We decided to take exposures in filter u anyways, science images should be okay we just suggest not choosing comparison stars from this region -had a light haze throughout the night and multiple close downs due to high humidity and heavy cloud cover
