                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st & 2nd Shift: Noel Camron Hastings
     Opened the enclosure at about 16:40 to begin cooling. Heaters were
on all day and dome was dry and clear. The cirrus was thick early on, but
then cleared up some. I took flats for the second half SPIcam users in
case we had to close later on due to clouds moving in.
     The Echelle ran smoothly and pointed well, despite our 2+ arcsecs
seeing first half. Switched over to SPIcam at halftime without incident
and UW ran for the rest of the night through variable clouds and bad
seeing.
