Today afternoon, the CH calibration activity started three hours later (due to the request to give to ISC more time to work and exploit the long lock that eventually ended at 16.42 UTC - entry 54067).  

We continued the NI CH calibration started Friday 27 November 2021 (entry 54005). 

We switched off the NI DAS and CH at 17.26 UTC to cool down the CP.

At 19.26 UTC, we switched ON the NI CH at 220 mW. Then, the NI CH power has been decreased to the nominal value (160 mW)  at  21.52 UTC.

Also the NI DAS actuators have been switched ON at the previous powers (see tab 1).

We left the arms locked on the IR.
