| 22:00-04:00: Carsten: Switching to 186-24. 1spindle error at the start. Weather becoming instable, tau fluctuating ~0.4 with clouds moving through. Pointing on 0851+202 showing quite some instabilities. Switching to test and trying Mars. Pointing stable on Mars and on 0851+202. Focus ok. 22h25: Start of wsw observation of J0956+3625, which still needs 3.5h. Scan 143 interrupted by spindle error at 23:34. One wind alarm during scan 145: 20m/s peak. Wind increasing with average values of ~10m/s. Scan 153, wind peaks at 20m/s, tracking errors reach 3". Pointed wobbler switched observations at elevations up to 84.0deg. Wind peaks reach 21m/s -- too high. Stop at 00:45. Start again at 1:15. 89deg elev is too high - cancelled.

Daily Reports
Observers on-site: Michael Mattern, Marie-Anne Carpine, Paul Law, Carsten Kramer and Stergios Amarantidis (AoD).
Operators: Gloria (day), Sergio (night).
All times are in Local Time.
Feb 18th, Tuesday
Maintenance: during maintenance CD fixed E1 (apparently the issue was found) and we conducted some tests with E0,1,2,3 (just tuning in some corresponding frequencies for each band).
15:00-22:00: Stergios: Basic training on NIKA2/EMIR observations. 15:00 LT: Wind gusts up to 20m/s thus we wait a couple of minutes for the weather to improve. At 16:21 LT we started with tuning with EMIR to project 143-24. Spindle errors and homology at scan 18, 19, 20, 21 (good start...). Manuel and Gloria think that this is caused as side effect after working on the emergency switch. Reset solves this problem. Trying with the 143-24 project. It doesn't work (either a focus observation). JT was contacted, the operator restarted odp but still plots are not created. The chopper was the culprit as it had been left in manual mode, we repeat a pointing test to see if we get the data and it works! Moving ahead with the observations.
Marie-Anne: Observing 143-24, mediocre conditions, we did calibrations on uranus, mars and 0458-020. We are observing NGC1977, map 4 vert. and then maps 1 to 4 horizontal. Spindle error but no scan lost (when changing project to test). Continuing with NGC1977 - project 143-24 (using the source 0430+052 for pointing; brightest source nearby) completing a forth repetition on the vertical maps. The weather though is quite unstable...
