Sofia, Frederic, Tuan-Anh and Angel at the telescope since 10:30.
16:00-16:50 (local time); Angel: Starting system check. It was necessary to restart the BluePill for moving the telescope. DAQ started at 16:30 (lost KIDs: 18, 1, 38). Pointing on Uranus (scan 113); imbFITS files properly created. Despite we tried to keep the main dish as far as possible from solar radiation during the maintenance slot, a focus sequence check gave a possible correction far from the expected: sign of a distorted beam. End of system check and observations suspended at 16:50: Aleksej K. (OHB) requires the telescope for some tests.
18:00-00:00 (local time); Sofia and Angel: Resuming observations after OHB's tests. After doing pointing and focus on source 0736+017, we had a beam of 17.5 x 18.5. Completed repetitions of WB89-670 (1 repetition done, 1 remaining). Then switched to project 151-23 targeting cluster PSZ2G210 (5th repetition out of 6, 40 mins long). Waiting for complete relaxation of the telescope. Very stable atmosphere conditions, peak-to-peak variations below 2 Jy/beam. Moved to 0316+413 for a beam map in total power (scan 157), after pointing and focus. Moved to calibrator CRL618, set pointing 7.1 8.1. FWHM 17.16 x 18.17, calib_1scan (scan 159) with nikaw-23. Performed a skydip (scan 160). Then moved to the cluster PSZ2G206 for project 151-23, new pointing on nearby source 0735+178, set pointing 5.4 7.6. Completing final repetition of PSZ2G206 (6/6).
