Daily Reports
Observers on-site: Tuan-Anh Duong, Quang Nguyen Luong, Federico de Luca, Antoine Zakardjian, Ste B., and Stergios Amarantidis (AoD).
Operators: Enrique (day) and Pedro (night)
Wish from Nicola Ponthieu in Grenoble: if we take any other polarimetry beammaps, please switch on the external calibrator too.

15:30-21:00 (Stergios): The weather is still not good for NIKA so we start with EMIR observations. Starting with project 028-24 but we stopped at 16:08 UTC due to high instabilities and possible rain to come. The science source L694 seem to have no bright pointing sources around a ~40 deg radius, however checking at the SMA calibrator catalogue we get the source 1924+156 that is strong enough to be detected and its at ~5deg distance from our target. High wind and opacity continued until the end of the shift. [No observations]
21:00-03:00 (Stefano): I take over; the weather is still bad and windy (although within the 18 m/s limit). While waiting, enjoy a Summary of the past weeks. Evolution of this shift:
- At 22:30 UT we give it a try with EMIR, because tau225~0.7, but with no success. We stop again after 20 minutes.
- we try again at 23:50 UT (tau225~0.55), with the same result as earlier. Still very variable and windy (~14 m/s max).
- again at 1 a.m. UT. Finally success!!! The sky has stabilized and tau is good ~ 0.5-0.35 (except taumeter spikes). I start observing 017-24, three repetitions on B5_HSEdge (their only target).

03:00-9:00 (Tuan-Anh & Quang): Weather isn't good for NIKA, tau255 drops to 2.6 but doesn't stay for long time. So, we switch to project 009-24 after several scans for project 017-24.
09:00-15:00 (Federico): Starting the shift with Nika! problems with DAQ, corrupted file generation. We restarted it twice, and finally works. Bad kids 32,5,34 (array 1,2,3 respectively), run 81. Doing pointing and focus on Mars, a calib_1scan (scan 20241127s94). Good weather, tau~0.25 and stable (and decreasing), so done 2 reps to finish PSZ2G284 of project 091-24, even if the source would exceed the elevation requirement during the observation (i.e would go below 40deg, with avg tau_225 ~0.22) to avoid empty slots later.
15:00-21:00 (Antoine):
