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 17, 2019 Regular queue from SBF with Flamingos-2 and Zorro. Poor seeing and moderate wind expected. Poor seeing throughout the night. We observed band 4 targets, finishing three programs. From midnight we ran out of IQAny target, and we monitored waiting for better conditions that never actually show up.
Jun 16, 2019 Telescope closed due to ice on the dome and bad weather Telescope closed due to ice on the dome and bad weather
Jun 15, 2019 We will run Flamingos-2 and Zorro queue if conditions allow. Poor seeing, high wind and fog predicted for the night. Band 4 observations with poor seeing until 22:00, when a freezing fog shuttered us for the rest of the night.
Jun 14, 2019 Regular queue from SBF with Flamingos-2 and Zorro, if wind and seeing allow. Poor seeing and high winds during the whole night. Most of the time spent doing band 4 observations with Flamingos-2. We observed one Zorro target when the seeing appeared to be stable and decent enough, but unfortunately it got worse during the sequence.
Jun 13, 2019 Queue observations from SBF with Flamingos-2 and Zorro. High winds and poor seeing expected at the summit. High winds and very poor seeing throughout the night. We observed several Flamingos-2 band 4 targets during the first half of the night, until we ran out of IQAny targets.
Jun 12, 2019 Queue operations from SBF with F2. Clear sky is expected with average-to-poor seeing. The wind will be an issue tonight (medium-to-high) and we will pay attention with the Humidity (medium). The night was completely lost due to high winds and terrible seeing. We opened, but the conditions were very bad, even to try to observe B4. We only observed one target in B4.
Jun 11, 2019 Queue operations from SBF with F2. Clouds are expected in the second half of the night with average-to-poor seeing, low-to-medium winds, and low humidity. The seeing was very bad and the clouds arrived in the second half of the night. We could only observe B4 in CC70/80 and IQany conditions. Two FR.
