              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Finally a night we could stay open all night long.  We had some clouds to deal with off and on but nothing threatening.
The 2nd program finished a little early due to their target going past the alt limit of the telescope.  This allowed the PAO to go up into the dome and start work with their instrument.  We were up there until around 5AM (4C, Brrr....) then we came down to the warm control room to finish observations.
