              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I beat on the S-H to make sure the stage was moving correctly and repeatedly back to the same position tonight, in preparation for the engineering run in a few nights.  All seemed to work fine now.  Outside temps were around 11C.
GFP started warming at around 03:45, I re-filled at 04:45. It was filled at 14:45 yesterday afternoon, so that is a hold time of only 13 hrs. I also re-topped the instrument off when I closed at 05:30.  PR submitted.
No problems other than the GFP tonight.
