              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
Clear sky in early night with 1.6-arcsec seeing. As yesterday, I had problem in fcusing triplspec because the star considered for focusing drifts upward during sweep procedure. I resolved it by center-selecting above the star.
Quite heavy cloud between 10 and 12.
First half observer signed off a little in advance because of high airmass of her targets and clouds at low altitude. Partially cloudy up to 4am, then clear.
