                   ------------- ACTIVITY LOG --------------
  1st Half Observing Specialist: B.Ketzeback
  Clouds and radar returns kept us closed all of first half. At about 2100
  the echelle started warming up. Verified that the transfer dewar valves were
  open and that the ion pump was working. I called Mark when a force fill from
  Russet failed. He described to me how to do a manual override fill. I found
  a large ice buildup on the camera. After defrosting many moths from their
  icy graves I did a manual fill and the instrument cooled again to proper
  temperatuures.
  2nd Half Observing Specialist: J. Dembicky
 Clouds, passing fog, high humidity, and a couple snow flakes (nothing
 sticking).  The echelle seemed to fill for the 2nd half.
