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.

Show nightlog summary for the night of:

Jan 17, 2018 This is a normal queue night with GMOS and F2 on dark time. The forecast is for clear skies and very good seeing. Very productive night despite the problem with IRAF/Pyraf/Ds9 on sbfcon02. It started on IQ85 until 2am, then it was solid IQ70 for the rest of the night. We observed two SToO, we completed one program and we made very good progress on one rollover program. All four of them are Band-1 programs.
Jan 16, 2018 Dark night with GMOS and F2 queue. We expect a clear night with variable seeing. It was a clear night starting with IQAny but improved to IQ70 before 11pm. We manage to observe three Band-1 programs including a RToO, one Band-2 program and one Band-3. We had some incursions to IQ20 and we attempted one Band-2 program for such condition but they didn't last so we had to drop it and go back to IQ70 programs.
Jan 15, 2018 GMOS and F2 queue. Clear skies and moderate seeing are expected for most of the nigh. The forecast is high humidity and a small chance of precipitation from the east. It was a clear night starting with IQ85. The seeing was highly variable the first half of the night changing between IQ70 and IQAny within 30 minutes or so. The second half of the night was IQAny and ended on IQ85. We managed to observe two Band 1 programs including a RToO, and one Band 2.
Jan 14, 2018 GMOS, F2, and GPI queue, expect clear skies and moderate seeing. Clear skies and good seeing all night. Several programs observed in bands 1 and 2.
Jan 13, 2018 Most of the night is dedicated to classical C-1 with the classical PIs connecting via eavesdropping. The remainder of the night is for GMOS, F2, and GPI queue. Entire night lost to weather. Thick clouds over the summit the entire night coupled with high humidity the second half of the night.
Jan 12, 2018 Queue night with GMOS and F2. We managed to observer one band 1 and three band 4 programs under CCAny/80 and solid IQ70 throughout the night, though we did lose four hours to clouds. There were reported a few faults, however, special attention has to be taken to check the MCS (El drives) as we did not really know what is the root cause of the fault.
Jan 11, 2018 Queue night with GMOS and F2. We managed to observe eight programs, four band 1, three band 2, and one band 3 under CC50, and solid IQ70 most part of the night. Overall, an excellent observing night.
