              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
During checkout, it was noticed that the rotator was visibly off when it returned to "zero". Since there was time, performed a zeroing of the rotator. We were off at 3.521 degrees. Also during checkout, the mirror tert status sppeared to freeze (it was at -36 seconds till collimation and counting down when I noticed). I issued a fake slew and that seems to clear it up, thank goodness. Evening was clear and calm with great seeing. No problems. We were open all night.
