              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
Target of Opportunity NM06 for the first hour
Then Apollo. Good data for both.
Then UVa tested a specific mask they brought for a cluster. The mask
appeared to be wrong so they turned back to standard observations with DIS
(1.2 arcsec slit with Hi Res gratings).
Had to close the dome at 22:58 because of high humidity (82% with
difference between primary mirror and Sloan dew point less than 2
celsius). Dew point sensor of the 3.5 m was still stuck below 0 C while
sloan's indicated 1.1 C.
We mounted Spicam at midnight, then we remount DIS at 3am with changing
wheel and adding a neutral density filter on the guidng camera i prevision
of Jupiter observations.
We give up at 4:30. No hope of improvement.
