              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend, C.Gray
We had thin clouds for the first part of the night that we were able to observe through, and then it cleared up nicely!
Focused echelle at high airmass.
KOSMOS cart roller rear left side while facing telescope nut came off, I threaded it back on.
Echelle internal quartz lamp seems to have died at some point during the night, submitted PR2168.
