                  ------------- ACTIVITY LOG --------------
 Observing Specialist: N.Camron Hastings
     I opened this evening after calibrations to allow cooling at about
18:45. All systems started and ran normally (except for a REMARK bug, email
was sent to Bob Lowenstein) Sky conditions were excellent until about 3am
when random clouds wandered through. Nothing too bad, and seeing was great
all night though.
