                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scale
 Was 580 Measured 578.3, 576.9; 577.6 changed to 578.0
 Alt Vel Scale
 Was -606 Measured -607.0, -604.0; -605.5 n/c
 The outside air temp dropped more than 25 degrees F over a 12 hour time
 frame last night as a cold front moved in. The resulting weather was
 clear skies but very high winds prior to sunset. We were able to open
 shortly afterwards but seeing was rather poor all of the first half
 and for the first few hours of second half.
 The change to the echelle resulted in a change a small change in pointing
 at that port.
 NA1 Tertiary Tilts
 TertXTiltCoef was 1029.0 changed to 1000.0
 TertYTiltCoef was  750.0 changed to 1030.0
 No other problems tonight.
