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
Jun 24, 2018 The forecast is for clear skies and poor seeing with multi-instrument observations with NIRI, GNIRS, and GMOS. A rapid TOO has was triggered before sunset, and we expect to observe the target and observe poor seeing programs throughout most of the night. The night started off photometric with very poor seeing due to the higher winds on the ridge. We observed a rapid TOO and other queue programs using GNIRS, GNIRS, and GMOS. The seeing stabilized in the later part of the night and we were able to observe good seeing photometric condition programs.
Jun 23, 2018 Multi-instrument queue observing minus GNIRS. Forecast is for high winds and poor seeing with clear skies. A good night with lots of band 1 and 2 observations. The telescope was well behaved.
Jun 22, 2018 Mulch-instrument queue observing minus GNIRS. Forecast is for clear skies and decent seeing. The first half was good but between very bad seeing and a major fault most of the second half was time loss.
Jun 21, 2018 Multi-instrument queue with lots of band 1 and a rTOO observation. Forecast is for clear skies and good seeing. A good night with clear skies and mostly very good seeing. Observed a number of band 1 and 2 programs and a rTOO observation. The telescope was well behaved.
Jun 20, 2018 Mulch-instrument queue observing including GRACES. Forecast is for evening fog and clear skies after that. Night lost to high humidity.
Jun 19, 2018 Mulch-instrument queue observing also with GRACES. Forecast is for clear skies and poor IQ70 seeing. Night lost to high humidity.
Jun 18, 2018 Multi-instrument Queue with Graces on the telescope. Weather calls for clouds but dry and stable conditions. The night started out with high and thin cirrus with great seeing. We were able to complete three observations before the fog rolled in for the rest of the night.
