Inmarsat-5 F4 arrives today at 83.5°E.
Expected to be an in-orbit spare at first.

The moving speed was slowing down, and Inmarsat-5 F4 may have stopped at 58.0°E (listed at ITU), but that's not yet confirmed by TLE.

New TLE shows Inmarsat-5 F4 is still moving 0.9°W/day, near 56°E now.
Starting to think, almost a year after launch, Inmarsat don't really need this satellite quite yet...

Inmarsat-5 F4 is now stationary at 11.0°E.
Not an Inmarsat location I think, so what's this new satellite doing here, reserving someone else's slot? :confused

Indeed, 3 months slot reservation time at 11.0°E (September thru November).
Since today, Inmarsat-5 F4 is back at 56.5°E.
