| '''16:00-19:30'''; Angel, Stefano, Ioannis, Hervé, Kaiyi: Tuning after maintenance and at a high elevation of ~70 deg. Bad kids 13/2/16. Pointing and focus on the quasar 0316+413. Beam size ~ 17.7 x 18.5" at 2mm. Small ellipticity remains also after focus. Atmospheric stability at ~ 2-5 Jy/beam for 2mm data. Training session for Hervé and Kaiyi on NIKA2 pool observations. Skydip [scan 20240220s82] and then started with project 150-23. After initial pointing loaded an OTF map on source "id307" but observations stopped after only one scan was completed due to wind velocity exceeding the limit (reached ~ 14 m/s). Tracking deterioration was also visible up to the point that we stopped. | '''16:00-20:00'''; Angel, Stefano, Ioannis, Hervé, Kaiyi: Tuning after maintenance was very good (bad kids 13/2/16). It was done at high elevation of ~70 deg. Then we did pointing and focus on the quasar 0316+413. The beam size for several pointings remained ~ 17.7 x 18.5" at 2mm. The small ellipticity seemed to remain also after focus corrections. Atmospheric stability was ~ 2-5 Jy/beam for the 2mm data. Around 17:00 we started a training session of NIKA2 observations for Hervé and Kaiyi. Then started observations of project 150-23 and did also a skydip [scan 20240220s82]. After initial pointing, we loaded an OTF map on source "id307" but we had to stop the observations after only one scan was completed (around 19:30) because the wind velocity exceeded the limit (reached up to ~ 14 m/s).

2024 Feb. 20th, Tuesday
Ioannis, Kaiyi, Hervé, Philippe, and Stefano arrived at the telescope.
Maintenance: the telescope and NIKA2 are healthy. The HWP has been tested and rotates correctly. All is ready for a great week
