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 skydeep at 2:46. We started a flux calibration at ALFORI and moved after back to a pointing at 0851+202.
