                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 The observer had some connectivity issues and problems downloading
 images at the start of the night that lost most of twilight.
 On one of the early objects there was some question about pointing
 and a quick pointing check resulted in the following changes to
 tert tilts.
 NA2 Tertiary Tilts
 TertXtiltCoef was -131, measured change 55; changed to -76
 TertYTiltCoef was 1026, measured change -112; changed to 915
 Clouds moved in soon after sunset and the observer quickly exhausted
 all their bright targets. Near midnight I closed for elevated dust
 counts since the dome dust counter was removed as a second spare
 yesterday I could not measure how effective changing ventillation
 configuration would be. We never reopened.
 No other problems tonight.
