              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Weather was clear or mostly clear, with variable seeing, but aside from that a smorgasbord of challenges kept me hopping tonight.  First there was trouble with our domain name service which made it difficult for all users to connect to APO and/or see their data.  I took care of guiding for the first observer, and there were no interruptions in data taking.  ARCSAT had many crashes tonight, in addition to getting lost after maybe hitting a limit or maybe something else.  APOLLO did not have tchnical difficulties but was still very difficult because of the moon phase and poor seeing.
