              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk,R.Mcmillan
Rain at the start of the night.  Borderline closure-level humidity for several hours after the rain cleared out.
The TSL dewpoint sensor was frozen, the optidew sensor may have an insect inside so we were relying on the sloan TSL and the inside optidew sensors.
