Night report 2017-08-28
The night's conditions were not photometric
Observers: Joe Lyman, David Homan
Support team: Lluís Galbany
TAT: Joe Anderson
Calibrations: EFOSC: bias, arcs
Conditions: Clear sky but strong wind. Seeing stayed below 1.5" early in the night. Jumped above 1.5" around 4:30 and stayed there.
Telescope had to close due to wind at the end of the night, cutting short our standard star exposures
