              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I reset drive controllers for alt, az, na2, agile
I zero'ed rotator -0.164
We were closed for the first could of hours waiting on humidity to drop.  We finally opened around 21:20 and I let the NM01 observer get their observations  (since they had been clouded out most of this month).  That lasted for just about 1 hour and then the humidity spiked again.
Instruments filled at 02:00
With clouds moving in and possible radar echoes, I gave up at 03:40
