              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We stayed closed until 23:35 due to clouds.  When we finally did open it didn't take long for the clouds to return, but we tried shooting through them anyway.  The clouds were not helpful for IR observations.  The first half observers didn't have much luck collecting useful photons thru the clouds and gave up early since they were not getting anything useful at all.  The 2nd half program used the extra time.
Seeing was excellent when we opened but by the end of the night the winds changed and the seeing went south.
No problems tonight.  Telescope parked at 104,70 in case of rain during the day.
