                 ------------- ACTIVITY LOG --------------
 Observing Specialist: N.C.Hastings, J.Barentine
     We opened the dome tonight at 18:10 MDT to allow cooling. John
Barentine, our new part time operator, performed the entire setup and
checkout tonight. We then operated the lens monitoring program and then
turned over to UC for science with the Echelle.
     One minor glitch tonight restarting the echelle guider ICC. It appears
that you cannot restart the Mac and allow the NFS login window to remain
there for long or else it causes problems. Basically, this means that you
must wait while it is restarting and then enter the password ASAP, then
continue with checkout. Craig is looking into this issue.
     Upper air disturbances moved in around 23:30 and seeing became
unbelievably bad, making echelle obs very difficult. (>5 arcsecs at times).
The temperature was very erratic and focus was jumping back and forth.
