              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
First half was clear with good seeing, but some windshake troubles.  The wind was around 30 mph from the NE, but the telescope struggled quite a bit in the NNW where I could see the azimuth struggling.  Then one position in the NE was not all that bad, which made me wonder if the wind direction was different for the dome vs the anemometer.
Second half started out clear but some high clouds moved in halfway through
