                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Az vel. scale: was 571, changed to 576
 Alt vel. scale: was -634, changed to -630
 Tonight was one of those perpetually-approaching, never-arriving
 storm systems.  I probably could have worked through some of the
 thinner clouds during first half, but I was expecting the rain to
 start Any Minute all the time, and it never did.  Second half, the
 storm made a more serious attempt to reach us, and we did get 100%
 humidity for a bit, but still no actual rain.  Argh.
 I got a fair bit of work done in-dome, but the list of things that
 needs to be done on-sky is not getting any smaller.
> spicam TUI software testing
Did some of this but couldn't do detailed testing without getting on
sky.  Flat script appears still broken?  Comments sent to Russell and
Craig.
> Agile inst block troubleshooting
Updated inst block, couldn't test it off-sky but it should be correct
now.
> new dis high res grating alignment  and characterization
Aligned and calibrated, appears to have similar throughput to
previous grating.  No chance for real throughput measurements.
> checkout with new tertiary galil code
Exercised tertiary in rotation and sent Russell a reasonable guess
for expected errors.
> tracking performance altitude tuning performance
> collimation check
> fastcam II data  for top end - see bill's email
> check  pointing
Not possible off-sky.
