              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Weather was mostly clear, occasional thin high clouds.  Some excellent seeing  in the middle of the night and moderate seeing towards the end of the night.
The first observer finished her eclipse observations sooner than expected.  We used this time for basic engineering tasks and observer specialist training.
