Daily Reports

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

Nov 17th, Tuesday

16h00 - 21h00; Bilal: System check, acquisition started, observing setup. TAPAS is not recording new scans (reported). Opacity is pretty high (0.7 < tau_225Ghz < 1, strong instability). Monitoring strong pointing sources aiming for reasonable point corrections. Science observations started: project 029-20.

21h00 - 24h00; Laurence and Frédéric: We take over from Bilal and continue observing on project 029-20 until the targets reached El.~20 deg.

Nov 18th, Wednesday

00h00 - 01h00; Laurence and Frédéric: Opacity increases up to 0.6-0.7, with large fluctuations. Targets of NIKA2 Pool scheduled projects are not feasible.

01h00 - 09h00; Ángel; Stavroula and Suzanne since early morning: taking over at ~01h and switching to EMIR; observing the four B213* sources (3 mm) of the EMIR backup project 011-20. Observations of the EMIR backup project 078-20 started.

09h00 - 15h00; Mónica, Stavroula, Suzanne, Carsten: observations for EMIR project 078-20 continued. Opacity going down; its mean value dropped up to about 0.45 around noon. Bilal helps with switching over to NIKA2 at 13h00 to start with 029-20.

15h00 - 21h00; Bilal: take over and continuing with NIKA2. Observing for project 029-20 since then.

21h00 - 24h00; Laurence and Emmanuel (Artis): Observations for project 029-20 continued. Opacities better than expected from the forecasts, with a nice opacity window from 21:00 and 00:00UT with a mean opacity around 0.3, that allows us to complete a whole iteration on sources. Note that the last 30 min spent on the project sources reached low elevations, from 21 to 14 degrees

Nov 19th, Thursday

00h00 - 03h00; Laurence and Emmanuel (Artis): We went to Uranus for pointing/focus and short calibration scans (calib_1scan). Opacity started rising soon after 00:00 UT. Strong indications of atmospheric instabilities from tau225 fluctuations and beam profiles on pointing scans between 00:30 and 1:30. We did two skydips, hoping they could be used despite instabilities. Indication of improvements after 1:30. We launched 2 pointing "probe" scans at high elevation and found reasonable beam profiles.

03h00 - 09h00; Alexandre: Mean opacity between 0.3 and 0.4 with some spikes during the shift. Two repetitions were carried out on TMC1-C and TMC1-CP for project 006-20. One repetition on JINGLE0 for project 061-20 after that.

09h00 - 15h00; Stavroula, Suzanne, Carsten: Weather stable (tau~0.3). We got one repetition (8 scans) on JINGLE16 of project 061-20. Continued since 09:30 on NGC2976 (24 scans) down to 30deg elevations and then on NGC5194 (2 scans) (project 160-16). TAPAS and (as no IMBFits) piic/ql frozen for a while (IDL/rta used instead). So, scans 61-66 haven't appeared yet in the TAPAS archive. At 13:54 local time the telescope decided to move to the zenith for no obvious reasons. The operator intervened and it did not happen again.

15h00 - 21h00; Bilal: Continuing on NGC5194 of project 160-16. Stopped since 18:30 due to wind gusts.

21h00 - 24h00; Frédéric, Juan: Observations resumed at ~22h. Weather conditions stable with tau just above 0.3. Pointing and focus on Uranus when starting the session. 12/16 scans on MOOJ2206, and 1/2 series of 16 scans MOOJ0319 (project 077-19).

Nov 20th, Friday

00h00 - 03h00; Frédéric, Juan: 2/2 series of 16 scans on MOOJ0319. Beammap on Uranus: 20201120s23.
