                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Russet McMillan
A patch of almost clear sky near the beginning of the night was
accompanied by high winds and humidity.  Later delights included heavy
clouds, rain, and fog.
 Observing Specialist, 2nd Shift: Jack Dembicky
Rain early and then high humidity conditions afterwards for remainder of
the night that prevented opening.  Changed LN2 tank on DIS (opened valve
after change and re-connected hose to DIS).  Filled Echelle LN2 tank as
well.  Opened/closed appropriate valves after fill. GRIM was also filled
as usual.
