              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Delayed opening until 21:20 due to clouds and virga in the area.
My 1st half observer gave up a few minutes early due to a few pesky clouds.
I managed to move the tert to NA1 via Bill's instructions and the wiki. The sky had improved by the time my 2nd observer finished their cals, so no time lost at the start of the night for their program.
We closed a little early again due to clouds this morning.  Humidity also started to climb at the end of the night, but I didn't see any rain threats on the radar.
No telescope issues tonight.
