              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Rain clouds moved through before sunset, but the outflow from the east front
combined with another system to the west to produce high humidity and horrible
seeing. Such that we were closed for a large chunk of first half.
Several Az Motion errors, almost all slewing in the SW.
Different high pitched oscillatory ringing when closing than I've heard before.
Ringing occurred when axes were stopped, covers closed but e-stop NOT engaged yet.
Stop button silenced the ringing.
SPICAM temps:
checkout 170.7
switch over 169.0
close 168.3
