              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with high winds and thin clouds coming through. Clouds grew thicker by 20:00, but eventually thinned again. Seeing was poor. Due to wind we had to aim for easterly targets. Around 23:00 the wind dropped and that restriction was lifted.  Still with poor seeing and high cloud, observer had trouble locating very dim targets.  Observers internet went down, so Obs Spec did some service observing (taking cals) until observer could log back in. The rest of the night was relatively peaceful, with better seeing and mostly clear skies.  Dcam was acting up again, but settled down a couple hours into its use. We were open all night.
