 Observing Specialist, 1st & 2nd Shift: Jack Dembicky
 A few scattered clouds at sunset. Enclosure was opened at 17:15
 (~sunset) for cooling.  Scattered clouds most of the first half of
 the night with occasionally thicker clouds passing thru.  A little windy
 at about 20:30 but the wind died back down a little while later.  I
 Closed the enclosure at 21:35 due to clouds and re-opened at 22:45.
 DIMM was closed at 21:35 due to clouds as well but not re-opened.
 Closed the enclosure again due to heavy clouds at 00:25. Re-opened the
 enclosure at 02:20. Closed enclosure due to temp/dewpoint closure policy
 at 4:50.
