                ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 AZ Vel Scale was 580.0  Measured 584.8 No Change Made
 Clouds thickened up around 01:00 and by 02:00 I could only see the
 brightest stars overhead.  I closed the mirror covers and waited, we
 never re-opened for the 2nd program.
 I did re-open at the start of the 3rd program and we were on the sky for
 about 30 minutes before the borderline humidity finally decided to rise
 and I had to close.  We never re-opened or the remainder of the night.
