Daily Reports

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

Jan 19th, Tuesday

16h - 21h; Bilal: Off to a rocky but good start in good conditions. Starting with project 138-20.

21h - 00h; Suzanne, Golshan, Hélène: Sh2_284 (program 118-20): 12 scans, with tau between ~ 0.3 and 0.22

• eFEDS3M (program 180-20): 6 scans, with tau ~ 0.2

We could effectively start only at 10pm, waiting for the scans in the queue for NGC2068 (138-20) to be completed. Then we observed for programs 118-20 and 180-20, as instructed to. The opacity went down to 0.2 and the sky was reasonably stable, but we had to stop before 2:30am while finally moving to our project, because the wind speed increased too much. Victor put the telescope in the stow position. We still encountered the problem of corrupted or missing imbfits files (preventing the IDL RTA) for two pointing scans. The first focus was difficult. Starting from -0.55, the first two attempts gave fits of -0.22 and 0.12, of bad quality, and the final successful attempt gave a fit of -0.01. The focus changed quite a lot during the night.

09h - 15h; We can move the antenna a bit. A bit of snow is stuck on the secondary, but we will see what we can do. The weather is rapidly changing. Array 3 synthesizer is not working after 2 reboots. I'll wait a bit and ask for a reboot later.

15h - 21h; Despite many tries and under a terrible weather, the synthesizer 3 does not reboot. We can't start array 3. Trying other solutions, but it's not time sensitive, as an heavy fog envelops the 30m.

21h - 00h; Stopped, foggy.
