              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, with poor seeing. Clouds came and went all night, wreaking havoc with our attempts to characterize the new baffle. Nonetheless, we took some data which we will reduce. We also ran a collimation check, and the numbers were good enough that no adjustment was needed.
