Observing Notes - 06/19/2017 Observatory: WIRO Observers : Bethany Garver, Kyla Jarka, Daniel Rivera Notes: -Took 7 sky flats on every filter (u, g, r, z, i) that where the planned observation filters for HAT-P-31 b. -Exposures using the u filter needed more than 500 seconds for good counts so we decieded not to observe in that filter. -We were able to observe without any problems the entire transit and about one hour before and after transit. -We took 40 biases at the end of the night.
