              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The night started out looking good, then the clouds to the west came in.  The first program gave up the last part of their time since they could not observe their target with the clouds. Finally around 00:40 it looked like something might be coming our way (other than more clouds) and we also finally lost our target with the echelle. I opted to close to be safe.  We had several passing sucker holes along with a steady stream of clouds the 2nd half that kept us closed.
