              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
The night started out beautiful, and then a cold front swept in.  Temperatures plummeted, humidity spiked, and we got a little bit of snow/frost.
The outside dust counter flatlines some time during the night.  Hopefully it is just frozen.
Had issues with guiding, email conversations were started.
