              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Opened just around sunset. Weather was perfect all night for engineering.
Motion error at 20:40 going from 80 to 43 at 73.5 deg.
Dataq restart at 21:55.
Switched back to arctic to redo throughput at 03:20. Failed to redo throughput because iraf was all wonky and I had no good way to check my work.
Gave up for the night at 4:30am.
Tasks Completed:
- tron and tcc restart
- iol reduction testing
- arctic throughput (was done very badly, see engineering email)
- ecam focus was checked and no adjustment was needed
- new ecam mask made
- inst block for khigh kosmos and klow done
- 100 point pointing model done and implemented
