              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
Restarted nicfps ICS at checkout.
DSSI is all packed up and put away.
DIS red ion pump started alerting around 11pm, but I went up and looked at the pump and the three lights were on and the number was updating and staying in the normal range. Thanks Bill for getting the software all sorted out.
Radar and clouds kept us closed most of the night. Opened at 2am, and closed from 3:30-4:30am for suspicious looking clouds forming overhead. Opened again at 4:30 and remained open until the dust spiked at 5:10am.
