15:45-21:00; Angel: DAQ started and tuning with 48/7/54 bad kids for Ar1/Ar2/Ar3. No evidence of correlated spikes in the noise spectra for all arrays. Tau(225 GHz) between 0.20 and 0.25 throughout the shift with some spikes. Pointing on Uranus (1.5, -11.6), larger in elevation than expected. NIKA2 mirrors deployment re-checked. Best focus -1.0 mm. Pointing corrections are stable at this position. Beam sizes: 12.9"/18" because of a slight ellipticity; beam shapes were quite reasonable. Good atmosphere stability: ~2 Jy/b at 2 mm. Checking pointing corrections (6 values) in ~70 < Az. < 120 deg, and ~45 < El. < 70 deg. We get corrections <Az.> = 3.2 +/- 1.4 and <El.> = -8.9 +/- 3.0. Refocusing and checking stability (~1-2 Jy/b at 2 mm). Science observations started with project 110-21 (2 reps. on NGC1333-C7). Then, 2 reps. on B213E (GASTON). Even more stable after sunset. The shift was finished with the observation of target WB89-793 of project 137-21. Stuck scans: 20220208s122 and s159.

03:00-09:00; Corentin : Started with a pointing on 1055+018, 2 reps on COSMOS project (little glitch of the tau for one scan) and finally another pointing. Moving to project nikaw-21 --> skydip on 1418+546 because of the burst of opacity but then tau stayed stable ~0.23. Moving to project 199-16, pointing on 1418+546 and 6 reps on PSZ2G087 (18/24 --> 24/24 COMPLETED). Focus on 1633+382 and then 2 reps on PSZ2G084 (16/22 --> 18/22). Last pointing and moving on PSZ2G084 because it was the closest from the pointing source : 1 rep (18/24 --> 19/24) and I launched another rep but there was a failure with array 2 so the scan was canceled (need to update the README and put 19/24 instead of 20/24).
