| '''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. | '''16:00-19:30'''; 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 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
