              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had a great night!!  The wind finally stopped, no dust, no humidity, no problems!  We had good seeing without a cloud in the sky but *lots* of galaxies.  I couldn't have asked for a better night.  Plus, it was nice and cold :)
No problems tonight.
