              ------------- ACTIVITY LOG --------------
 Observing Specialist:  R.McMillan
 We were able to start on-sky recovery from the shutdown tonight, but
 between weather and some problems not very much could be done.  I
 confirmed daystaff checks on the telescope motors, mirror motors,
 and the available instruments.
 After some evening storms cleared away, I opened the dome (with
 one false start) and started cooling the telescope.  A software
 problem prevented me from obtaining a pointing model, and a hardware
 problem with the guider video signal prevented me from getting
 Shack-Hartmann data for collimation.  However, using SPIcam I
 confirmed that both pointing and collimation are reasonably good, so
 it won't be difficult to fine-tune them once the problems are
 cleared up.
