              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
We had variable high clouds and borderline winds for much of the night.  But it was productive even so.  The engineering went well, with DIS focus work, collimation, and a pointing model.  Hopefully the telescope performance should be back to normal now.
dcam shutter was consistently open.  ecam shutter appeared to be behaving properly (and so did ecam readout).  ARCSAT was also very peaceful tonight.
