| Bad weather till 5:30. Start at 5:30. Calibrations for 017-24. Three repetitions then move to 009-29. Weather conditions improving. Pointing on 0736 (weak) then on Mars. At 6:30 swapping to NIKA2. No source available for beam map, post-posed to a later time (on 1226+023). DAQ started at 07:00; bad KIDs: 28, 4, 33 (ar1, 2, 3), sky-illuminated. Pointing on Mars. Software problem with the analysis of the pointing after a couple of tries.: QL doesn't work with run 80. Switching to run 79. DAQ restarted at 08:50; bad KIDs: 32, 2, 34 (ar1, 2, 3). Angel patched it. Pointing (-4.8 41.8) and focus (1.3) on Mars. Strong wind (20 km/s peak), tracking errors (small, +-2" on data, larger, 3-4" peak from Grafana monitor), Homology problems. Calib_1scan. n tracks to fix homology. pointing on Mars, then skydip. Weather is borderline for the scientific programs, switched to polarimetry to catch possible problems.

Daily Reports
Oct 29th, Tuesday
10:30; Federico De Luca, Stefano Andreon and Angel Bongiovanni at the telescope. Juan Macías can join in remote mode. Adverse weather: snow/electrical storm, strong wind gusts. A bolt stroke apparently affected the power supply of the anemometer at the station (to be checked after storm; spare part is prepared).
15:30-23:00; Federico, Angel: The syntheziser of array 1 was substituted by NEEL's unit and everything (cryostat health, noise traces, etc.) has been checked by Dave. The instrument is ready for observations. Telescope stopped, deicing on. Weather forecasts are adverse at least until midnight.
23:00-24:00: Juan, Angel: Bad weather continues. Wind gusts, despite tau_225GHz ~0.5. Deicing still on.
Oct 30th, Wednesday
00:00-07:00: Juan: Wind, snow.
07:00-15:00; Stefano: Still stopped. Wind, light snow.
15:00-23:00; Federico: Strong wind gusts. Snowing at intervals.
Oct 31st, Thursday
00:00-07:00: Juan: Strong wind (~25 m/s according to OSN anemometer) at midnight, dropping speed over the shift. Snowing until ~04h and tau_225GHz > 1.2 all the time. Deicing off at ~05:30. Snowing again since ~06h. Cloudy at dawn.
07:00-15:00; Stefano: Bad weather (strong wind, low visibility), yet better than previous days.
15:00-23:00; Federico: Anemometer repaired (~15:10). Wind speed about 10m/s, but it's a cloudy afternoon (tau~1). Waiting for better weather condition. At 17h the weather is much better. Starting scientific observation with EMIR, project 058-24. After first calibration, we moved to test account to check if all is ok & pointing and focus. tau_225 is continuously dropping. All ok, at ~17:30 started scientific obs. of 058-24, NOTF6V, NOTF7H, NOTF7V done. tau-225~0.6 for all the observation. Spindle error during NOTF7H, script interrupted and launched again. After NOTF7V, larger instability in tau and anomalous refraction evidence in pointing. Starting monitoring the weather under test account. Resumed observation of project 058-24, NOTF8h (21:55h). Then changed project to 017-24.
