              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Pesky clouds to start the evening, we opened since there didn't seem to be a threat of precipitation.
No problems tonight other than pesky clouds at times.
Observer took DIS dome cals in the morning so I left the instrument mounted for them.
