              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with low clouds and an eastern storm blowout. The dust spiked and kept us closed while under full clouds. Thing started clearing, but that's when the humidity went up. We weren't under fog, but everything was veeeeeery wet, enough to set off the rain sensor. I called it at GS01's cut off of 4am.
Dataq needed another restart tonight.
