              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clear skies all night.  Seeing was pretty bad just after sunset but improved toward the end of twilight, stayed good for a couple of hours, and then became variable when the wind shifted a little before midnight.  And then it got better again.
