              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started breezy and clear.  We were open all night but high thin clouds appeared after midnight and persisted until dawn.
The Ion pump on NICFPs spiked at 19:49 (UT151121 02:49).  The temperature did not rise on the instrument itself. After un-mounting the instrument I tapped on the steel cylinder coming from the square magnet and the pressure decreased to safe levels.
