              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out clear and calm. Nothing wrong found during checkout. Dome cameras have been down. PR was issued. First exposure of gcam showed no filters on menu. Did a paremeters to bring it back. Arctic filter scritp kept failing, don't know why, no time to figure it out so just focussed by hand. Skies stayed clear and calm, good seeing which improved after midnight. Dust started to get high by 03:00 but never exceeded safe levels. Press fans were turned on to combat the dust. We were open all night.
