                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az  Vel Scale was 586.0 measured 583.5, 587.5; 585.5 no change
 Alt Vel Scale was -626.0 measured -624.7,-627.1;-625.9 no change
 Took a pointing model at NA1 as part of the determination of new
 sag coefficients with the new tertiary.
 I was able to make a collimation check and altitude sweep with the
 Shack-Hartmann. Data will be reduced at a later time. I sent an
 image log on to Russet.
 Next I collected an hour of fastcam data.
 I gave the last 3 hours of time to Mike Skrutskie to collect some
 Triplespec data in exchange for time UVa gave us 2 months ago to
 align Fastcam.
 Second half experienced various thickness high altitude cloud cover.
 Seeng was excellent much of both halves.
 The last move of the tertiary tonight from TR3 to NA2 failed to close
 the clamp. Rehoming the E actuator corrected the problem.
 No other problems tonight.
