                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scale
 Was 579 measured 578.0 n/c
 Alt Vel Scale
 Was -604 measured -603.8  n/c
 Quite a bit of scattered to broken clouds the first half of the night.
 Skies became mostly clear to photometric during second half.
 There didn't appear to be any threat from precip so we were open all
 night. Seeing was moderate.
 No other problems.
