              ------------- ACTIVITY LOG --------------
Observing Specialist: H.Abbot

Dust particle readings on the weather status page went down before start of shift. No real chance of opening so wasn't a high priority to fix. Emailed Shane about it on Jack's advice.

Two dataq restarts required in the night.

Didn't open since it was cloudy with nearby rain all night.
