              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We didn't open due to the large amount of snow we got today and nearby radar returns all night.
Reset the agile heartbeat on nimble since it failed at checkout, no problems when tested later in the night.
Ran snow program.
We had light flurries (and/or snow blowing around off of trees and roofs) on and off throughout most of the night, as well as nearby radar all night.
Temp started at -10C, down to almost -13C and then back up a little to -12C at 06:00. Humidity about 90% at the start of the night, down to 60% by 19:30 and 40% by 06:00.
Telescope is parked to the south.
