Observers on-site: Maite, Mairi, Victor and Hamza safe at the telescope.
Operators: Pedro (daytime) and Sergio (night). Angel around.
Times below in LT (UT+1h), unless otherwise is specified.
Preparatory notes
Please, remember to use the focus value of Ar1 (roughly Ar2 + 0.65 mm, but use directly the focus Ar1 monitor if possible).
Please fill the Table with the Ar1,2,3 focus values as follows. At best, make one table per day.

Maite (15:30-19:00): NIKA2 cryo in good shape after cool-down. HWP checked with Dave. Starting system-check with NIKA2 (Blue-Pill checking asked by Jean). Clear skies, mild wind. Opacity tau_225GHz ~ 0.2 and rising. BluePill tests (new version) was OK. Rolling back to the previous version. We have some problems with homology. Pointing corrections far from the expected values. Fixed by Pedro. DAQ restarted with bad KIDs (ar1, 2, 3): 15, 7, 37 NIKA2-Pol. Quite stable. Starting with @calib_1scan on MW349, NGC7027, CRL2688 (scans 20251111s144-146). Doing pointing+focus on 3C454. Starting project 046-25: calib1_scan on 3C454, pointing on 1741-038, starting observations of target G24.78. Doing Pointing + calib1_scan on Neptune
Mairi (19:00-24:00): Still on NIKA2-Pol. Starting with focusing on Neptune. Calib_1scan on Neptune (scan 179). Switching to project 084-25. One rep. on S87IRS1. Some wind alarms time to time. Wind gusts of 17-20 m/s in the last minutes (21:55, scan 185 in progress). After the final scan, finished with calib_1 scan on Neptune (scan 190). High wind alarms again and the forecasts announce higher peaks. About stability, we had peak to peak variations of ~ +/-10 Jy/beam (2 mm) in the last scans. Telescope parked at 21:30.
