              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus, J.Dembicky
D.DeColibus started the night for his training with supervision by J.Dembicky.
Night started with moderate overcast clouds, but TSpec could push through.
Wind increased to borderline by 19:30. Had to close due to wind at 21:10.
Opened again around 22:50, with significantly clearer skies.
J.Dembicky took over for 2nd half of the night.
No problems 2nd half, clear skies.  Humidity just started to rise as we closed at sunrise.  Possibly some snow to our west but it hasn't crossed the county line when I finished tonight.
