              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Clear skies.
First focus run of the night had a significant shift. Temps were reasonable, not
much difference between ambient and truss. Second focus run about an hour later
secondary values were back where I would have expected them.
PMSS seemed noisy tonight.
Motion errors:
UT 01:38 AZ "Motion error too large"
UT 02:11 ALT "Motion error too large"
