              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
Mostly clear with very thin clouds; it got a bit cloudier over the course of A-half but still thin enough to observe through. Winds were fairly high for all of A-half and the start of B-half.
Closed at 23:14 due to wind gusts which got up to almost 50mph, opened back up at 01:00 when the wind speeds came back down.
Had to do gmech parameters to get the NA2 guider filters to show up.
CU03 finished observations at the start of twilight.
Temperatures were a few degrees above and below 0C with humidity around 30% at the start of the night down to 5-10% near the end of the night.
