              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
gcam needed a nubs restart at checkout and nicfps needed an init.
The arctic diffuser is struggling to move into position while right-side up but we worked through it no problem tonight. Also, our first good weather night since the snow storm hit us! Seeing was good to excellent and we got a lot of good data! UW01 donated 20 min of their time to UW09.
