              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night was completely cloudless and with low dust and humidity!  However, wind was an irritation and gave us poor seeing nearly the entire night.  The DIS B400 grating was changed out for the B1000 for UW04 program.
Tspec was corrupt (surprise, surprise) so I took darks all night.  The instrument came back to a good state at least twice but not for very long.
No other problems tonight.
