               ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scale was 583.0, measured 582.0, 586.7; 584.3. No Change.
 Worked with Matt N. to bring Triplespec back up after its recent
 warmup/cooldown. The main instrument Leech Controller would not
 accept commands until I power cycled it. Images appear normal.
 Had several tert clamp errors when tried to rotate to various ports
 tonight, homing E axis resolved each error. Report sent to Nick.
 Spent the evening collecting data to compare the effect of the new
 mirror cover paint. Also collected fastcam data and Shack Hartmann data.
 I was able to reduce the SH data and make an adjustment to collimation.
 With Russets help we found and corrected a sign error in the SH
 configuration.
 A bad sensor in the Control Building Fire Alarm system caused spurous
 alarms for most of the night. A PR was filed.
