| 03:00-09:00; Stergios: We continued observations of the project 009-22 (the source SU Aur is above 80 degrees to move to project 062-22). The data of this project were not stored correctly to the project’s directory. AS was contacted. We moved to project 062-22, however the weather improved so at 03:46 (UTC) we switched to NIKA. Data acquisition (repeated three times) have shown 61/8/85 bad KIDS for the Ar1, Ar2 and Ar3, respectively. Pointing/focus/calib1scan at Mars, moving to 1055+018 for pointing and then to project 089-22 (lower priority but higher tau+instabilities for the rest of the visible targets) with the source 1030+0135. The weather improved further (tau~0.3 - stable) so we stopped the observations of 089-22 (~30min total observed) and moved to the project 192-16 (COSMOS). | 03:00-09:00; Stergios: We continued observations of the project 009-22 (the source SU Aur is above 80 degrees to move to project 062-22).

Nov 15th, Tuesday
16:36-21:00; Stergios: No NIKA2 neither EMIR observations were conducted during due to high tau values (see following plot depicting the corresponding tau values for this time window). We performed a quick system check that started at 16:36 (after maintenance) checking only the tuning since we could not perform a pointing or focus due to the weather conditions. For training purposes of the current observers we initiated the data acquisition for NIKA2.
21:00-03:00; Lara: High tau values. No observations.
Nov 16th, Wednesday
03:00-09:00; Stergios: High tau values and rain during the whole shift with increase of the wind velocity. No observations.
09:00-15:00; Rodrigo: Very unstable tau measurements (0.2 < tau < 8.8). Rain and light snow for most part of the shift. No observations.
15:00-21:00; Israel: No observations carried at the telescope due to high values of tau (~5-8) and periodic rains. I attach a picture of the site during the late afternoon
21:00-03:00; Lara: It was not possible to observe with either NIKA2 (tau>0.4) or EMIR (high tau + highly unstable weather conditions).
Nov 17th, Thursday
03:00-09:00; Stergios: Started observations with EMIR at 5:32 under the project 079-22. We tried a couple of pointings which showed high variability in the atmosphere. We stopped around 6:00 due to rain. We started again the observations with EMIR at 7:46, trying pointing under the same project and stopped again at 8:09 due to high values of tau and the fact that we could not obtain a stable pointing. We repeated another data acquisition with NIKA for training purposes. No observations on science targets.
09:00-15:00; Rodrigo: Fog and light rain. High and unstable tau values. Telescope was parked. No observations.
15:00-21:00; Israel: No observations performed due to the foggy weather -high and unstable values of tau (~1-3)-. The whole shift was accompanied by periodic rains.
21:00-03:00; Lara: Due to highly unstable weather conditions and large tau values, it was not possible to observe.
Nov 18th, Friday
03:00-09:00; Stergios: High tau values, rain, fog, no observations.
09:00-15:00; Rodrigo: Heavy snow and high tau values. No observation.
15:00-21:00; Israel: High tau values, snowing, no observations.
21:00-03:00; Lara: Starting pointing test with EMIR at 22:30 pointing to Mars since tau values dropped to ~0.4 with more or less stable weather. We checked some pointings and focus, tau decreasing to 0.1 but there was a bit of instability still. Good pointing after focus, more stable weather, we decided to switch to NIKA2 at 00:30 (Local time). We performed three data acquisitions with the following number of bad pixels (i.e., Ar1, Ar2, Ar3, respectively): 41, 7, 63 | 38, 6, 63 | 43, 7, 61. Very stable atmosphere with tau values around 0.2. We performed a pointing and focus with Mars. At 1:51 am we moved to project 093-22 (higher priority projects not visible at the moment, or with not so great elevation for being observed). Pointing at 0851+202 (focus was done with Mars) go to the source PSZ2G186 (no need for another focus since FWHM 17.2x19). We performed a skydip at 2:46 [20221119s21]. We started a flux calibration at ALFORI and moved after back to a pointing at 0851+202.
Nov 19th, Saturday
03:00-09:00; Stergios: We continue with the observations of PSZ2G186 (project 093-22) with excellent weather conditions (tau~0.2, quite stable) until 04:04. We decided to move to COSMOS (project 192-16) performing a pointing/focus on 0851+202 again. The histograms from the data acquisition seem to deviate a bit far from the zero values with the histograms being a bit broad, although this drift should be attributed due to the long COSMOS scan (~52min):
We performed another skydip and at 06:36 [20221119s43] we switched to project 160-16, performing firstly a pointing/focus and then going to target NGC4254. High variability of ~10Jy/b at 2mm, we repeat the data acquisition and repeat the scans to test the variability (the Sun is rising which might have caused the effect). Tau is increasing so we move to the more relaxed project 089-22. We took good pointing/focus and we tried one scan on the source J0842-0157 however the tau is increasing, therefore we wait and possibly change to EMIR.
09:00-15:00; Rodrigo: We waited until tau values become stable and switched to preparations for project 095-22. NIKA2 data acquisition is performed before starting. 66, 8, 93 bad pixels in each array, but histograms do not stay close to zero. Sky covered and tau values keep unstable (2 < tau < 4) and increasing. Switched to EMIR (~10:00 LT). Started with pointing and calibrations. Atmospheric conditions get stable around tau=0.3 and switch back to NIKA2 (~12:00 LT). Data acquisition performed and 59, 7, 87 bad pixels found in each array. Observations for project 079-22. Pointing/focus and observations from target AR2747 (two cycles of eleven observations with pointing in between).
