             ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,C.Gray
We had threatening weather at the beginning of the night which improved
after twilight.  It was clear for several hours and then some clouds moved
in.  We were able to do basic checks of the telescope and half the
instruments, solved some problems and documented others for further work.
Our primary achievement was adjusting primary mirror collimation to reduce
coma.  More work is needed.
