              ------------- ACTIVITY LOG --------------
Observing Specialist: M.Croom
Russet came in and walked Mark through recovering a dropped quad on ARCTIC. We also had an error with NICFPS during instrument checks that restarting nubs cleared. Clouds prevailed all A Half and most of B Half. Opened for just over an hour but the skies did not support the science. Gave up at 4:12 and closed for the night.
