Operators: Frederic and Sergio

Jan 7th, 2025, Tuesday

Alice, Antoine, Juan, Tuan Anh, Wonju, Ste B. and maaaany others arrived at the telescope.

NIKA2 work fine, the HWP correct rotation has been checked. The new AoD, Stefano, is trained by Angel and Frederic with explanations about AoD specific tasks and safety measures. After maintenance and the AoD training, we start the operations at ~16:20 local time.

16:00-22:00 LT: Wonju + Alice, Stefano. We start with some training of the new NIKA2 observers, explaining in what a typical NIKA2 session consists and clarifying some specific features for NIKA2-pol. Then we proceed with the following observations:
- we start with polarimetry
- calib_1scan on MWC349, NGC7027, CRL2688
- 135-24: source IRAS21078 (... repetitions)
- when observing polarimetry, we monitor the instrumental polarization by taking roughly every hour one calib_1scan of either an unpolarized point-like source (Uranus) or a known QSO, depending on availability.
- skydip in between (scan 20250107s25)
- one gummy seal of one lower petal falls off at ~18:30 LT (not our fault, we swear, we're not trying to break the telescope ;)
- 166-24: four repetitions of CasA

22:00-04:00 LT: Antoine & Tuan-Anh. We switch to total power and observe:
- 188-24: ... repetitions of A0520
- total power beammap on Uranus, 99 sub-scans (scan 20250107s76)
- ...
