              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Nicfps needed an expose init after being mounted but was fine during checkout.  I suspect moving it upset it.
We had clear skies all night with good seeing. A cold front blew through around midnight but the winds didn't get too high and the temp didn't drop too much. Dust counts started going up but we stayed on open.
