              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear skies and decent seeing... and dust, gradually rising over the course of the night until I closed at 2 am and it continued to rise.  Happy springtime!
NICFPS had an error at checkout but recovered with 'nicfps expose init'.  Echelle at one point had an error when moving from lamps to sky where it said the mirror hadn't moved all the way, but it was apparently out of the beam as we were able to see just fine on the slitviewer.  No time was lost to these issues.
