              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Observer started early to take echelle cals.
ARCSAT was having issues tonight.  After the observer gave up I tried further investingating the problems.  Unfortunately the humidity closed the 3.5m which closed ARCsat.
Our secondary and structure temps were lower than the outside temps (and over the closure limits for most of the time we were closed tonight).
My 2nd half observer gave up around 04:50.
