              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A lovely clear night with moderate to good seeing.  Everything went well for the first program, then APOLLO had trouble communicating with the CAMAC electronics.  I spent some time wiggling cables and power cycling to try to wake it up, but after a while I gave the remaining time to the following program.  Likely something got disturbed as a result of work earlier in the week.
Aside from APOLLO, everything worked well.
