                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
 Enclosure fans/louvers were started/opened at 16:00 for cooling.  Opened
 the enclosure at 16:50 and turned the instrument over to the observer at
 17:10 under clear skies. 20:10 closed due to dust. I was informed that
 there is a controlled burn near Cloudcroft and the wind shifted
 directions and blew the smoke this way. Opened enclosure at 22:40 after
 the dust levels dropped below the acceptable levels for 15 mins.
 Observing Specialist, 2nd Shift: Noel Camron Hastings
   Second half started as soon as the dust cleared. All ran smooth. No
odd sounds heard all night from the enclosure.
