              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started out with mostly clear skies, but clouds in the southwest started coming in growing thicker through the night.  The first two programs were able to run in their entirety. During the UV04 program, clouds grew too thick to collect data, and we shut down for a while.  We attempted to collect data again during what became a sucker-hole, and closed down again. We did not open again.
