Dec. 6th, Tuesday
10:30-15:00; Stergios: No observations. Sub-reflector out of order, the team is repairing it at the moment. The problem was identified at the backplane which was replaced. High opacity with low wind. We switched and configured the new run (i.e., run74) and everything seem to work in order. Data acquisition was also conducted with bad pixels of 30, 7, 51 for the array 1, 2 and 3, respectively.
15:00-21:00; Juan:
21:00-03:00; Quang: We observe the project 105-22, Tau225 was about 0.18, P2P fluctuation was 10 Jy. We did 4 scans of B213-16 (s42 ~ s45), after that we did a POINTING, focusing on 0439+360. We did skydip and POINTING to 0529+075 around 22:10 then focusing & calibration. At last we did 7 scans of B213-16 (s60, s19~s24).

03:00-08:00; Jean-François: Finish up project 105-22 (B213-C6) started by Quang. Over the night, opacity was "high" between 0.3 and 0.45 but the atmospheric fluctuations were fairly low (< abs(+/-10) Jy/b peak-to-peak at 2mm). Start with focus and beammap on 0316+413 (3C84) with stability ±3Jy/b at 2mm. Project 159-22 (NGC1569). During last hour, project 169-22 (GJ526North) when other projects were too low in elevation. Stop early at 8:00 local time because of POLAMI.
08:00-10:30; Albrecht: (POLAMI)
10:30-15:0; Maintenance + System check
15:00-21:00; Juan:
21:00-03:00; Quang: No observations due to high tau.
Dec. 8th, Thursday
03:00-08:00; Jean-François: No observations due to high tau/wind.
08:00-11:00; Albrecht: (POLAMI - no observations).
11:00-15:00; Hélène: No observations due to high tau/wind.
