                 ------------- ACTIVITY LOG --------------
 Observing Specialist: J.Dembicky
 I started cooling the enclosure around 18:50 tonight and opened the
 enclosure around 19:15 under clear skies.
 Everything ran smoothly all night until twilight when the observer
 reported Spicam not responding.  After about a minute it came back to
 life and things seemed to run normally (it froze and then ran really
 slow before going back to normal speed.).
