              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
No issues with nicfps or the all sky camera tonight! The night was clear with good seeing until the winds shifted. We had blow out from thunderstorms hit around 3:30 and the seeing was destroyed. And then the humidity and dust started spiking. We closed near 5am due to dust and were not able to reopen.
No problems tonight.
