              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Discovered a problem with the DIS turret motor during checkout.  I had to manually move the turret
for 2nd half observer.  Lost about 24 mins in the process.  Turret motor will be inspected, by the
day staff, tomorrow.  Please put B400/R300 gratings in place if not able to repair.  PR Submitted.
Mirror covers needed to be cycled at switch box on telescope, eyelids worked under remote control
but not mirror covers.  Resetting fixed problem.
We had heavier cirrus at the start of the night, it cleared out for a while then we dealt with
thinner cirrus towards the end of the night.
Clouds formed in the East at the end of the night and made APOLLO observations uhm... challenging.
DIS slitview stars looked normal tonight (we had worse seeing than last night).
