              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We stayed closed untill 21:00 due to clouds and nearby storms.
A surprisingly good night despite not looking too promising at sunset and a poor forecast.
We did have poor seeing, 2.0 arc sec, at the start of the night.  The seeing improved during the 2nd half.
