| 03h - 09h; | 03h - 09h; Longji: The observation started at 3:20 LT when the last scan of the previous shift was completed. I first observed COSMOS until 5:45 LT. After doing focus on 0851+202, I switched to GOODS-N until the end of the shift. The pointing was checked every 1 hour. The weather was clear and tau values were around 0.15 during the shift. |

Because of the pandemic, no observers can come to the telescope. This pool is entirely in remote mode.

16h - 21h; Bilal, Angel: Started about 15h (UT); tau(225GHz)~0.15, stable conditions. One beammap (s161: tau~0.13; El.~41 deg.) & calib1scan on Uranus. Pointing & calib1scan on secondary calibrators (MWC349, CRL2688, NGC7027) and 2251+158. Target tmc1-cp (project 096-20) observed for 1.5h. Project finished.
21h - 03h; Angelos, Suzanne, Hélène: Calibrations done: focus twice and skydip once. Atmospheric conditions: tau between ~ 0.12 and 0.17, stable pointing corrections and beams (2mm FWHM ~ 18"), relatively small sky fluctuations. Observed sources (program 160-16): NGC925 (8 scans, ~ 177 min), NGC2976 (6 scans, ~ 49 min), and NGC5194 (2 scans, ~ 48 min). We lost about 1h15 at the beginning of the shift because of a difficult setup of all the needed windows. Initially, they were split up between VNC 30 and VNC 32, which is not practical when observing remotely with a tiny laptop screen. Many thanks for the help received in the process of setting everything up nicely on VNC 32! We also lost time when switching to the pointing quasar for our last source, and back, because of the azimuth limits. Will know better next time.
