                ------------- ACTIVITY LOG --------------
 Observing Specialists: J. Dembicky
Az Velicity Scale measured 580.7 was 587.4 changed to 581.0
Alt Velocity Scale measured -634.3 was -635.4 no change
I checked pointing of the telescope with Saturn and Regulus.  Both were
spot on with SPIcam.
Worked on Fastcam and found out that there was a measurement wrong for the
port that was being used.  Nick will have to machine an adapter so no
Fastcam alignment or data could be completed tonight.
We then took Shack-Hartman Data to
Russet did echelle tests and everything looked good.  Pumping definately
did help.
Wind changed direction and around 00:30 the wind really picked up (over
closure limits).  Dust counts also went high and smoke could be smelled
around the site.  There are several fires burning in the Lincoln National
Forest and the wind was blowing smoke from one or more of the in our
direction.  Humitidy also went over the limits as well.
We never re-opened and I closed up around 04:00

     Note: the wind was coming from the azimuth listed.
     The convention used is north=0 degrees, east=90 degrees.
     The dust count is particles > 1u per 0.1 cubic feet.
