| 03:15-09:00; Angel: Observations of L1544 (EMIR backup project 043-22) continued. We stopped for a while two times before ~04:30 due to atmosphere instability. A PWV between 6 and 9 mm in the l.o.s. (MRTCAL) after that. A total of 9 reps. were observed. Changing to project 051-22. Telescope parked at 06:05 after trying the first pointing scan due to repeated motor current alarms (wind speed around the limits). | 03:15-09:00; Angel: Observations of L1544 (EMIR backup project 043-22) continued.

Observations resumed at 06:40; still being on project 051-22: NGC 1977, 1 rep. of map4-vertical, and 1 rep. of map1-horizontal. Stopped again at 07:45: pwv rising above 11 mm, unstable atmosphere. Again, wind speed is close to the limit. 09:00-15:00; Gianluca: 15:00-21:00; Emilia: 21:00-03:00; Matt: |

During the maintenance slot, the OS of nika2-b machine was updated and rebooted (PM, JT, WR) as planned; DJ switched to the 2nd trap of the NIKA2 cryostat, HP pressure/MC temp. checked, temperature timelines and noise traces OK after that.
16:00-21:00; Angel, Emilia, Matt: Telescope parked due to the wind. System check OK (t07 account).
21:00-03:15; Matt: Weather is definitely not good enough for NIKA-2, but luckily the wind has calmed down so we can observe. After some initial problems with weather at about 22:20 we got on sky for project 018-22. Tau is horrendous and not that stable, but we seem to OK for this bright CO line. Carried out 1 rep. of domapC1, PWV reading still between 7-11mm, moved onto C2. During C2 cal's now report 11-14mm above threshold - had reduced by next scan. 1/4 way through C3 scan but then had to abort due to wind. Just after one hour we restarted by atmosphere stability was terrible, but waited 15 mins and we were good! After a few pointings, cals started observations for 043-22, performed 8 times 12 min observations.
