                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scale was 579.0 measured 572.6, 574.2; 573.4 changed to 573
 No problems tonight, nice clear skies with moderate seeing. The first
 high altitude clouds from hurricane Dolly reached the site at 04:00.
 We saw one servo error at UT07:19 on the rotator with Triplespec during
 a slew but that was quickly recovered, no time was lost.
