              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Clouds at the start of the night.  We finally opened around 19:00 for about an hour and then clouds came back in again.  We re-opened at 22:30 and stayed open the remainder of the night.
Observer was taking echelle cals in the morning so no IOL.
