              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Eh, a bust of a night, as expected. I opened at sunset but only to a sky that had completely clouded over. There was a tiny window were we were able to get a little data, but nothing of significance. Around midnight the humidity spiked and we got some light snow. After that, more clouds, humidity, and high winds. Things cleared around 4am but the wind was gusting over 40 mph. We gave up at 5:30 am.
I parked the dome south just in case there was any snow accumulation on the top of the dome.
No problems tonight.
