Night was not photometric Observers: Joe Lyman, David Homan TAT: Morgan Fraser, Giorgos Leloudas Support team: Giorgos Leloudas Calibrations: EFOSC: bias, arcs, sky flats (i,R,V, and B partly) SOFI: imaging and spectroscopic Conditions: Clear start of night, seeing ~.7". Increased seeing to ~1.2" at 2:00, clouds moving in from the West. Around 4:00: ~0.5", rising back to 1.5" about 6:00.
