The observing team at Gemini keeps a detailed log of each night's science observing, also noting weather issues, technical faults and any time spent in planned engineering. It is read by Gemini staff early each morning. A summary of the night is written at the end of observing and included at the top of each night log. That summary is posted here, unedited, to give interested users a feel for what we're doing.

UT DATE NIGHT PLAN NIGHT SUMMARY
Jul 08, 2021 The maintenance works on the secondary went through the whole day and identified a major hard disk failure in the CEM computer. A new disk will installed next early morning.
Jul 07, 2021 Although most systems were recovered following power issues caused by the earthquake yesterday, there are ongoing issues with the secondary system which started on Sunday night and need continued work tomorrow. Time loss attributed to FR-72114.
Jul 06, 2021 Night cancelled due to a 5.2 magnitude earthquake at 13:42 HST that caused power issues and left various systems in a state that will still need to be recovered before resuming normal night time operations. Details summarized in FR-72115.
Jul 05, 2021
Jul 04, 2021 Expected to be clear all night with average seeing. DD104, Q205 are priority targets. Conditions were CC50/IQ70 all night. First half of night contended with some faults, second half went smoothly. Observed many band 2 targets, with some band 1 and 3 thrown in.
Jul 03, 2021 Forecast calls for clear sky with moderate seeing. DD104, FT212, Q126 are priorities. Skies were clear, but seeing did not meet expectations. Did mostly band 2 and band 3 programs.
Jul 02, 2021 Forecast calls for clear sky. Q116 is a priority in all bands. DD104 is priority if weather allows. FT212 also a priority. Tested out the old/new FT 212 run and its way of doing things. Condition stayed clear but IQ85 most of the night, so did some band 3s.
