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
Sep 25, 2018 GMOS+F2+GPI queue from SBF We spent most of the night in Band 4 due to clouds. At the end of the night conditions improved and we attempted GPI observations which were abandoned due to wind shake. At the end of the night we lost some time due to an issue with M2.
Sep 24, 2018 Last of five GPIES campaign nights, with GMOS, GPI and F2 backup from SBF. The forecast is for variable conditions.There is a chance of passing cirrus (CC70), alternating with clear skies (CC50), variable seeing, mostly poor (IQ85), however, it might improve towards the middle of the night. GPI campaign most of the night. We had some thin cirrus in the first part of the night, however they disappeared after 2:30am. We measured IQ70 until 22hrs, after that we did not have values from Seeing Monitor. One Band-1 observed.
Sep 23, 2018 Fourth of five GPIES campaign nights, with GMOS, GPI and F2 backup from SBF. Forecast is for mostly clear, but there is a chance of cirrus after midnight (CC50/70), poor (IQ85/Any) seeing, and moderate (< 10m/s) winds. Most part of the night was dedicated to GPI campaign. We also observe Band-3 and a standard. The weather remained clear with CC50 and IQ70.
Sep 22, 2018 Third of five GPIES campaign nights, with GMOS, GPI and F2 backup from SBF. The forecast is for clear sky (CC50), average (IQ70) seeing, and moderate winds (< 10m/s). We observed under photometric and poor seeing conditions. GPI team observed several targets but after 1am basically was Band-4.
Sep 21, 2018 Second of five GPIES campaign nights, with GMOS, GPI and F2 backup from SBF. The night is forecast with high level clouds during most of the night (CC80/70), average to poor seeing (IQ70/85), and low (< 5m/s) winds, but it might increase during the night, staying below 10 m/s. GPI observations all night, with a couple of faults. Observations were taken under CC70/80 and IQ70 conditions.
Sep 20, 2018 First of five GPIES campaign nights, with GMOS, GPI and F2 backup from SBF. The night is forecast to be cloudy for most of the night (CC80/70), there is a chance of improving in the second half, towards the North. But more clouds will arrive afterwards. Seeing conditions will be average to poor (IQ70/85), and expected winds of 10 m/s. Overcast until 5am (dome closed), after that the conditions were CCAny IQ70. We observed three Band-4 programs.
Sep 19, 2018 Normal queue night with GMOS and F2 from SBF. The forecast predicts high-level of clouds all the night (CC70/80), average seeing (IQ70/85), low winds (< 5m/s) but with some wind gusts ~ 15m/s at the beginning of the night, and high humidity (60%), probably it starts to go down around 40% at midnight. Clouds present throughout the night, the conditions changed between CC70-CCAny and the seeing was mostly IQAny. We observed two Band-1, one Band-2, one Band-3 and two Band-4.
