              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had a lot of rain threats at the start of the night that never materialized.  The clouds were pretty challenging, though.  Eventually I thought it was safe to open and we struggled through the murk for a while.  The scheduled second half observer checked in and concluded the clouds were too thick for her science, so I let the first half observer continue for another hour and then I did pickup engineering until the clouds got too thick again during twilight.
