Starting from the entry 56320, at 06.59 UTC I stopped the HWS-DET acquisition (WF 500) and the NI RH steady state curvature can be seen in figure 1 and its centre coordinates are Y=(-0.06 +- 0.03) cm and X=(2.84 +- 0.05) cm.

At 07.21 UTC I started a new HWS-DET acquisition and at 07.26 UTC NI CH was switched on @ 368 mW. The NI CH steady state curvature can be seen in figure 2 and its centre coordinates are Y=(0.16 +- 0.06) cm and X=(-0.7 +- 0.1) cm.

There was a misalignment of (3.54 +- 0.15) cm in the horizontal direction and only (0.22 +- 0.09) cm in the vertical direction. So, I decided to move the CH in the horizontal direction, but several issues were found with TCSPicoNI which did not allow me to improve the alignment (see entries 56326 and 56328).

At this point, I set the NI CH power of June 28th (see entry 56314):

At 16.37 UTC HWS-DET acquisition started in order to see the RH cooling phase and at  16.52 UTC I switched off the NI RH.

At 19.55 UTC HWS-DET acquisition stopped, nothing of interest emerged from this measurement.

Further investigations are needed to understand what happened to the picomotors on the Hot Mirror. These will require accessing the bench.
