              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A great night tonight! No clouds or wind, there was some dust after midnight that was at borderline of closing but we were able to make it through until dawn. Seeing was moderate and the CU class got a ton of targets on sky! Enough to take some time at the end and do some "eye piece" observing. Fun was had by all!
No problems tonight
