                 ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Jack Dembicky
Enclosure fans were turned on & louvers opened at 16:15.  Enclosure opened
at 18:15.  Seeing was reported very poor by the Photometric Telescope
operator
Clouds moved in at 20:50 and I closed the enclosure at 21:25 due to
thickening clouds.
 Observing Specialist, 2nd Shift: Russet McMillan
 Despite some thinning of clouds between 1 and 2 am, conditions
 were never really good enough to open.
