              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
There was a motion error at 71 alt when coming from 80 during checkout. I did a reinit and had no further problems.
Pollen was a bit high tonight but not nearly as bad as yesterday. We were able to stay open all night, sometimes with good seeing even if the wind was coming from the east! There were some clouds around 1am and 3 am but they weren't a big deal and left rather quickly.
