                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az velocity scale was 573 measured 576.8, no change
 Thin to moderately thick scattered clouds most of the night.
 First slew of the evening put the target just off the field of view
 of agile. I corrected pointing with tertiary tilts.
 The observers target of the night was at a declination of 34 degrees
 and rising. Tracking behaved very well. The observer reported that the
 stars on the field drifted just 10 pixels (2.6 arcseconds) over 1.5
 hours! The drift was in the azimuth direction. This is excellent
 confirmation that the new altitude controller is working well since
 rotator and azimuth speeds are slow in this part of the sky and
 altitude speeds are high.
 Nicfps quit reporting temperatures and pressures tonight. I could
 not get them to restart. A PR was issued.
 Second half went well. The APOLLO crew has some internet problems
 however both observers were logged in from hotel rooms.
 No other problems, everything worked well. Seeing was excellent.
