| 21h - 00h; | 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. |

| 00h - 03h; | 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. 09h - 15h; Jean-François: Observed GASTON 122-16_dust sources (top priority source L1689b) for 3 hours and then GASTON 122-16_GP (cycling thru the 3 sources) for 1 hour. Excellent weather through the run. Only issue: focusing was difficult at 13h (LT). It took a source away from the sun to succeed. The telescope had been observing the whole morning at about 30 deg from the sun. 15h - 21h; Angel: Continuing on GP_L24p5 of GASTON, and then 1 rep. on GP_L23p9.

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