              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend

Overcast with storms nearby and/or actively raining on us all night long. We got some 40+ mph wind gusts and high humidity too! We did not open. 

Dataq plots were frozen and I tried restarting things with odd and unsuccessful results. Email sent to Cary with more info. 

ARCTIC fine today (Tencl appx 15C at checkout). Script taking 1 ARCTIC bias exposure per hour left running.
