              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan,M.Croom
A smidgen of afternoon rain left some lingering radar traces, delaying
opening to near the end of twilight.  Seeing was decent despite a
brisk east wind, which can be one indicator of a monsoon state!
Russet and Mark did the instrument change, and Russet stayed until
ARCTIC was focused. The cloud state was variable, but the seeing at
switchover was unchanged from the earlier measurement. The observer
was able to collect data all through morning sky flats.
After parking the telescope for the night, a Reverse software limit error
was encountered, where Alt was showing 0 when it was actually at 75 degrees.
Russet talked Mark through the reset procedure, and all is well now.
