After half an hour a worsening of the sensitivity curve has been observed and the RH power has been reduced to 2W (17.22 UTC).
To be investigated.
The RH has been turned OFF at 17.44 UTC.
We analyzed the HWS wavefronts and the RH curvature is clearly visibile in the maps, this means that we are enough centered on the TM (see image in attachment).
The measurement of the NI absorption is postponed to tomorrow morning shift, because of the unlock of the IMC (see operator report).
