16:30-21:00; Ioannis & Alice: Maintenance finished at 16:30 but wind was too high to start with observations. Wind speed reduced a bit by 18:00 and started system check with EMIR because Tau225 was ~0.4-0.5 at that time and expected to increase further. Observations for EMIR backup project 056-22 between 19:00 and 21:00 for objects G053.23 and G49.48 until atmosphere became too unstable to continue (pwv fluctuations between 6mm and 10mm). All NIKA2 *.ini files and IMBFITS creation scripts were updated for ongoing run73.
21:00-03:00; Hélène: Tried a couple of pointings but atmosphere was too unstable. Observations stopped at 21:50 due to high wind speed.

03:00-09:00; Philippe & Tuan-Anh: EMIR backup observations throughout the shift, first for project 051-22 (one set of maps on NGC1977) and then for project 079-22 (a couple of repetitions on P07-C and P01-C). Opacity high and quite variable (Tau225 ~ 0.5-0.8).
09:00-15:00; Juan Macías & Alejandro: EMIR backup observations for project 083-22 (39573-high; 2 sets of repetitions) until 12:30. Stopped after that due to very unstable atmosphere and fog (prediction shows showers this afternoon).
15:00-21:00; Alice: Weather too unstable (Tau225 ~ 0.5 - 1) and a bit of snowfall. No observations.
21:00-03:00; Hélène & Juan: Opacity decreased and we switch finally to NIKA2! 
Tested acquisition in both total power and polarization mode and system seems to work fine. Bad KIDs are about 70/5/90 for Ar1/Ar2/Ar3. After several tunings the bad KIDs of Ar3 remain at this relatively high level but not too much (80-90). Several pointing, focus and calibration scans on Uranus while we wait for the opacity to decrease further. Note that calib_1scan scans 20221109s150 and skydip scan 20221109s151 were taken at relatively high opacity and not too stable conditions and calib_1scan scans 20221109s161 and 20221109s162 were taken with the HWP in front of the cryostat window. Around 22:30 UT the opacity reaches a plateau around 0.3-0.35 and baseline variations are < 1 Jy/beam at 2mm, so we do a proper calib_1scan [20221109s171] and a skydip at lower opacity [20221109s172] and we start with observations for the GASTON LP (122-16)...

03:00-09:00; Philippe & Tuan-Ahn: We switched to NIKA2-pol around 03:30 and did a few calibration tests on Uranus and Mars (polarisation-mode calib_1scans : 20221110s[36,37,44,46]) and also a polarization mode skydip [20221110s45]. Focus was stable but opacity and atmospheric stability were marginal. nk_rta did not work in polarization mode (idl_polar). Then we switched to total power around 05:30 and after a couple of calib_1scans on Mars and CRL618 [20221110s53 and 20221110s54, respectively] we observed project 008-22 (a pair of maps on IC348-1, Tau225 ~ -0.2-0.25) and later project 095-22 (2 sequences on AR2623, Tau225~0.2).
