              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
A bit windy during the afternoon, but the dust mostly avoided us. Thin clouds bothered us during A-half, but they dissipated after midnight and it was clear during B-half.
We closed up at 12 degree twilight. For some reason the ARCSAT weather script in ACP was preventing AS05 from taking lamp flats, so I disconnected the weather script temporarily.
