              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started with rain nearby and dark clouds but, somehow it cleared up enough to open for over an hour! Then, a wall of rain came from the north. I didn't think we'd be able to reopen but, miraculously, it cleared again and we opened at 4:30 am!
Around 2am nicfps started sending out alarms about temperature. I went an filled the instrument and all was fine. I'm not sure what happened... Maybe I thought it was filled and spitting when it wasn't? Or I didn't tighten the screw cap enough? I filled it agin at 6am just to be safe.
