                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scale
 Was 580 Measured 581.8, 579.9; 580.8 n/c
 Alt Vel Scale
 Was -606 Measured -607.0, -604.1; -605.6 n/c
 We were open all night however cloud cover was pretty thick. There
 was no threat of precipitation. The Venus program could barely make
 out the planet through the clouds at very high airmass. The observer
 said that the data they collected was not usuable at all. The second
 program of the night was monitoring a bright target at much higher
 altitude and the clouds thinned some for the rest of the first half.
 At midnight the clouds thickened again and there just was no hope
 of looking at extended objects. We held out until 5am and then
 gave up for the night.
 No other problems tonight.
