Observing Specialist: T.Sutherland,R.McMillan
Restarted gcam at start of night.
Opened the dome at 18:38. Lots of clouds and small threat of precip at the start of the night. We had shockingly good seeing at the start of the night.
Clouds were a consistent pest throughout the night.
Closed at 6:15 for cals. No echelle iol end of night due to cals.
No telescope or instrument problems tonight.
