              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
During the day today, NA2 rotator lost connection and had to be reset in talk2boxes at the start of the night (PR2065). The ARCTIC ion pump controller was also in an unhappy state (possibly associated with time on generator power today?) and needed to be power cycled. The NA2 eyelid also had trouble opening (PR2134).
We lost about an hour and a half to clouds that we couldn't observe through at midnight, but we stayed open because the weather was fine otherwise. The clouds continued to be annoying for the rest of the night, but DSSI was able to observe through most of them.
Temperatures were around 5C most of the night, humidity around 30%.
