                  ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Barentine
 Opened the enclosure at 19:20 to start cooling.  Skies were mostly clear
with some cirrus; this situation was decidedly non-photometric enough to
cause the first half observers to change their plans instrument-wise.
Seeing was variable throughout the first half and the skies continued
non-photometric, but otherwise mostly clear.
 Conditions were similar throughout the second half.  Seeing was variable,
winds light, dust low.
