              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
ToO program first hour of the night. Mostly clear.
GFP had some trouble and needed the Newmask #1 to be power cycled (twice), but then
appaerently recovered fine.
Don notes about DIS: "The blue images look fuzzy, perhaps just the wings of the
seeing image. But it could also be frosting on the chip. Has anyone checked it
lately?"
