              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The night started out with high dust and wind. Both calmed down enough to open about an hour after sunset. However, during switch over, the wind started gusting near 40 mph and we had to close again. Once the wind calmed down the dust stayed elevated for another hour. But B half was able to get a couple hours on sky AND tcam worked perfectly!
No problems tonight
