                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Velocity Scales:
   At checkout 582.28, 579.57; 580.9 was 583.0. No change made.
 Cloud cover was too thick at the start of the night so we stayed
 closed until 22:30.
 Dust levels above closure limit all night but with the press fans
 on and louvers closed we were able to stay open all night.
 No other problems.
