                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
 16:35 started dome cooling fans/louvers opened. 16:40 Opened enclosure
 for cooling. Turned the telescope over to the first project at 16:55.
 Clouds moved in at the end of the first program which prevented the
 second program from starting on time.  They took darks and flats while
 they waited for an opening in the clouds (which never happened).
 Observing Specialist, 2nd Shift: Russet McMillan
 After a sprinkling of graupel before midnight, the skies cleared
 suddenly around 01:45, as soon as the Sloan Observers had all given
 up.  The telescope was opened at 02:10, and we had about half an hour
 of clear skies and good seeing before more clouds started to appear.
 Another clearing later on gave us usable time until dawn.  The
 telescope and instrument behaved perfectly for all of this.
