Because of the pandemic, no observers can come to the telescope. This pool is entirely in remote. This week: Nicolas Ponthieu, Alexandre Beelen, Juan Macias, Laurence Perotto, Florian Kéruzoré, Stavroula Katsioli, Hélène Roussel, Florian Ruppin
A new sweep was performed.

High winds with gusts up to 40m/s

With hail!
No observation could be performed so far.

It's even raining in Granada. No observations.

Morning shift. We can start the observations, the opacity is excellent and the weather is much better, but we can't start science because we lack a beammap to reduce data. NP, AB and BL perform observation of Venus with NP reducing the beammaps successfully. Grenoble is warned about the presence of the beammaps, but the quicklook with PIIC won't be ready before Monday. The IDL pipeline is used instead !
We let the weather slowly stabilize until we can finally start observations after the sunset. Opacity throughout the evening: ~0.2
LPSZ starts science for this pool (ACT-CL-J0223)! ...

...followed by IMEGIN over the night shift (NGC628, NGC925) and 037-20.
Morning shift observes project 074-20 and 077-20.
Source of 077-20 is 5 degrees from the sun and while it did not hurt the science observations for a while, it ended up dramatically changing the beam parameters for the worse. So we let the antenna relax in front of M16 (029-20)

15h00 - 21h00; Ángel: Opacity about 0.15-0.20. Observed 6 reps. of G82 (007-20) and 1 rep. of HD143894 (039-20).

08h00 - 09h30; Matthieu: Stopped at 09h00 because of high opacity. Maintenance works since then.
16h00 - 21h00; Ángel: High opacity (0.7<tau<1, strong instability). Switching to EMIR at ~18h for stability monitoring. Backup observations with EMIR (project 073-20) until ~21h00 with slow opacity decreasing. Then, switched to NIKA2.
21h00 - 00h00; Miren, Jean-François & Juan: Pretty bad weather. Opacity at about 0.6. We observed 029-20 following Bilal instructions.

00h00 - 02h00; Miren, Jean-François & Juan: Pretty bad weather. Opacity at about 0.6. We observed one more hour for 029-20 following Bilal instructions until source too low. Stopped since ~02h because of high opacity.
15h00; F-Xavier Désert: opacity at 0.6 (but decreasing). Backup observations with EMIR (Mónica: project 153-19). We start observing with NIKA2 at 17 UT. Lots of anomalous refraction, going on and off. Moving to different pointing sources to get a decent focus.
21h00; Jean-François, Miren, Juan: relative good weather opacity around 0.3->0.2. Started observing MOO (Ruppin et al) and XXL clusters (Ricci et al). Good beammap on Uranus at around El.=0.60 and opacity 0.3. We observe since yesterday that box 13 is fully flagged by nk_rta, this should be investigated.

00h00; Jean-François, Miren, Juan: We observe ACTJ0240 for LPSZ project 199-16
