              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
During check out: ecam needed restarting; GFP temp alarms began at 4:55 pm showing
the the heater current was changing; also the fill gauge on the echelle nurse dewer
seems to be sticking.
Same weather pattern as yeaterday: afternoon building of local clouds/storms.
TSEPC guider struggled with faint star guiding. High sky background, clouds + dust +
moon, like observing in city lights. Tried using NA2 guider for guide corrections
but cannot maintian guide star through nods. Later when the thin cirrus cleared the
guider seemed to perform better.
