Print this reportComment to Instability of the ISS in long term locks (24745)I checked the same channel with more precisely.
The behavior of change of the PMC trans DC power was quite different when ISS locked loss(Fig.1., Fig.2.) and naturally PMC power became lower(Fig.3.). For Fig.3., as already described by Akutsu-san, we sometimes detected the sudden worse alignment of PMC, we also need the investigation For Fig.1. and Fig.2., the fluctuation of PMC trans DC power was much faster than Fig.3. it will be occurred in other reason, I think.
