              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A dust spike delayed opening at the beginning of the night.  After that, we had high clouds which started out thin and got thicker during the second half of the night.  There were also some borderline winds for a while which kept us from pointing west.
