                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scale Was 579 Measured 574.5 n/c
 Alt Vel Scale Was -603 Measured -604.5 n/c
 Unsettled weather most of the night. Seeing was poor to moderate.
 We were forced to close for 2 hours at shift change because
 of overcast skies and then high humidity.
 No problems.
