              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Despite the very poor forecast and a power outage, I was able to open for a few hours of our first shutdown recovery night.  I got a rough adjustment to collimation by tilting the primary mirror, but further collimation work will be needed (hopefully with a more thoroughly-cooled telescope).  ARCTIC and Echelle slitviewer and NA2 guider all need some TLC, but other instruments appear ready to go.
