||GSAOI night with GMOS and F2 as backups
||A challenging clear night where the seeing got progressively and steadily worse. We managed to get a few GSAOI images at the beginning, but then we had to resort to Band 3 and Band 4 programs.
|Oct 18, 2018
||Second night of GeMS/GSAOI run. GMOS-S and F2 available as backup instruments. Expect clear conditions (photometric) and good seeing.
||Finally, we could observe some GeMS/GSAOI program under decent seeing conditions. Obtained data for 3 GeMS/GSAOI programs with an FWHM of 100 mas and strehl of 14%, in average (K-band). We were guiding at 300 Hz (LGS) most of the time tonight (good photon return).Other GSAOI programs were attempted to observe, but the LGS loops were very unstable, which prevented us to obtain good data. We also observed two B2 GMOS programs and GMOS calibrations (twilight flats). Overall, a good night.

||Second night of GeMS/GSAOI run. GMOS-S and F2 available as backup instruments. Expect clear conditions and variable seeing.
||The very poor, and some time, atrocious seeing (IQAny most of the time) prevented to observe with GSAOI tonight. We attempted to observe several GSAOI programs, but never obtained a good performance, despite the relatively good photon return. The best correction we had was 0.20 arcsec
at 2.2 microns, not enough for the GSAOI programs. We managed to observe a few programs under
poor conditions. Two band 2, one band 3 and one band 4 program. The band 3 program is completed.

||First night of GeMS/GSAOI run. GMOS-S and F2 available as backup instruments. Expect clear conditions and variable seeing.
||Started the night checking the laser constellation. We experienced few faults related to the laser during the checks. The GSAOI on-sky checks are completed and new Instrument Origin and WCS calibrations were derived. Unfortunately, the variable seeing (between IQ85 and IQ Any) prevented to obtain any science data with GeMS/GSAOI. Despite the bad seeing, we managed to observe two Band 2 programs and some calibrations.
|Oct 15, 2018
||Clear conditions, average and better seeing and low winds expected. Multi instrument queue observations with F2 and GMOS-S.
||Clear skies the whole night, seeing variable, starting with IQ70 and then softening to IQANY and then back to IQ70 at midnight. In spite of variable IQ a productive night. Observed three GMOS Band 1 programs, three Band 2 GMOS programs and one F2 SV program,
|Oct 14, 2018
||Expect Clear conditions, median seeing and low winds.
||Night lost to freezing fog.
|Oct 13, 2018
||The night is forecast to be clear, winds moderate, and humidity on the higher side. We will try to knockout the queue build-up and hopefully proceed with the F2 ENT.
||The night crew arrived to SBF to find clear skies on the summit! We opened right away to clear some of the pending twilights. We spent a lot of time on the F2 ENT tonight, but we got some good diagnostic data in the end. Spent the rest of the night on queue and in weather loss.
