              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
It was partly cloudy all night; thin enough to work through during first half, but second half the clouds were thicker and the target fainter.  Although the dome was open until nearly the start of morning twilight, much of the time there was no hope of getting usable data.
We kept NICFPS pretty close to upright during all observations, and the pressure was fine all night.  The first half observer was working slightly defocused so I didn't get a real seeing measurement.
