Daily reports, NIKA2 pool week #4, Winter 2024-25 semester

First week of the NIKA2 run 71 (Cryo run 83).

This time, 8 days, starting on Monday, instead of 7 starting on Tuesday. Change of plans: we will go up to the Observatory on Tuesday as usual, hence 7 days.

Observers on-site: Philippe André, Helena Mazurek, Chiara Mininni, Ioannis Myserlis (AoD), Monica Rodriguez, Ste B. (AoD)

Operators: Kike and Frederic

NOTE by SB: if possible, please take some total power beam maps (Uranus at best); and some pol beam maps on Uranus too.

Note by CK: During the holography run last week, several panel frames of the primary have been adjusted. Uranus observations were conducted on 10/11 Feb with EMIR. Telescope efficiencies may well have changed (slightly improved).

Feb 10th, Monday

The plan has changed. Spindle nr 6 is being replaced today and the operation will take until tomorrow, end of maintenance. Therefore the observations will start tomorrow.

Update on the Spindles work: yesterday the wind was rising, hence there's not been time to change the spindle motor. All electric connectors have been checked and few were found loose and have been fixed. The sub-reflector was mounted back in place. Few hours of EMIR observations were carried out as a test. During these few hours, three Spindle errors occurred.

Mama, don't worry, I'm safe! We missed our beloved telescope

Chiara, Helena, Ioannis, Philippe, Stefano and maaaany others arrived to the telescope.

During maintenance, we prepare the NIKA2 setup: we open the VNC, start XEphem, start the PIIC monitors, start the make-imbfits (old). We test the rotation of the HWP: all works fine.

16:00-21:00 LT: Chiara + Helena + Stefano: wind, the telescope is parked. Training the new observers about how to read the PIIC monitor, fill Tapas, fill the Daily report, and everything they've ever wanted to know about what we are going to do when the wind will give us a break.

21:00-03:00 LT: Helena + Stefano; wind and snow -> telescope parked

Good morning! Chilling

03:00-09:00 LT: Ioannis; I start the observed around 5 a.m. LT. Progress of the morning:

09:00-15:00 LT: Philippe

15:00-21:00 LT: Chiara + Ioannis: a test by Ioannis using a quarter wave plate in front of the NIKA2 rotating HWP is scheduled for this afternoon. This experiment allows to detect circular polarization with NIKA2! It is combined with X-POL observations of the same targets. SMA 1mm observations were also carried out this morning.

21:00-03:00 LT: Helena + Stefano
