              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tonight was the target for many observations and opportunity for the trees...  We had two ToO request, one from UW12 and another from UW13.  UW13 took A half from OU03 and we observed a comet with three tails! Almost as cool as a three headed dog.  Seeing was moderate to poor and the sky, while relatively clear of clouds, was not clear of pollen.  UW13 must have sensed this and they did not go ahead with their ToO.
I closed the dome at switch over after monitoring the pollen.  The clouds continued to stick around but there was no rain. It looks like pollen season is finally upon us. I think I hear Barry White somewhere out in the woods...
No problems tonight
