APACHE POINT OBSERVATORY SDSS 2.5M OBSERVING LOG Monday June 15, 2026 (SJD 61207) ---- Observing Team ---- Audrey Oravetz John Downey (support) Katie Grabowski (support) Tracey Naugle (support) ---- Observing Summary ---- A large majority of the night was lost because of lightning, clouds, and some humidity (4.3hrs). We managed to open though just before 07:00Z and observed with only APOGEE exposures 1-2 designs before thick clouds returned (loss of 3.6 additional hrs). ---- Automatic Summary ---- Time Field-Design-Conf DesignType BOSS/APOGEE Seeing Overhead Complete?
