 Observing Specialist: B.Ketzeback
 Az Vel Scale
 Was 574 measured 576.2 n/c
 Alt Vel Scale
 Was -606 measured -604.1  n/c
 Another frustrating weather night with a lot of clouds, high winds,
 dust and humidity. We opened for a short while each half.
 No other problems.   APOLLO ceded their time to the preceding
 scheduled program due to laser problems.
