              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We were able to open at the beginning of the night in good conditions, paused in the middle for some thick clouds, closed for a while for a cold front to come through (with spikes in wind, dust, and humidity), then reopened to push through clouds until almost twilight.
UW students being trained: David Fleming, Hannah Bish, Jacob Lustig-Yaeger, Kolby Weisenburger
