              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
Echelle temp -107 @ 00:34UT
Sky cleared in the late afternoon but at sunset clouds re-appeared which delayed our opening.
I received a RotDTime=0.8; BadRotDTime: TotD=1.0 warning during checkout that I couldn't seem to
clear with repeated axis stop/stop button/axis init commands.  Rotator seemed to work though even
with the warning.
Skies finally cleared up around 21:20.
Clouds started to increase again around midnight and we fought for a few more hours.
