              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Dataq needed a restart at checkout
Nicfps read out 0's on first exposure for JH03, though it was fine during checkout. However, I mounted nicfps between checkout and JH03 taking their image.
We have clouds hanging around at sunset that came and went with good seeing but then, from out of now where (it actually came from the east) we had sudden high winds, dust, and humidity. I closed at 22:30 as the clouds started forming over us as I wasn't sure if there was rain in them.  Winds gusted to nearly 40mph and then the humidity spiked.  Things didn't calm down until nearly 3am, at which point everything cleared and we had just awful seeing.
