Next, Intallation sequence:
- SSRMS in move to align HTV-X to Harmony nadir Node-2 CBM.
- HTV-X CBM visual inspection (ISS cam).
- No exercice constraint.
- Final alignment.
- RTL "Ready To Latch" position.
- 1st stage capture: 4 latches closed "soft capture".
- SSRMS in "limp mode" (no constraint on HTV-X by SSRMS).
- 2nd stage capture: 16 bolds drived (2nd stage capture: 16 powered bolts are commanded to complete the rigidization of the structural joint to seal the vestibule between the passive and active elements.).
- Installation complete.
- Vestibule leak check.

That's SSRMS grapple, not Harmony bething. I estimate the latter at about 1840  UTC soft capture 1850 UTC firmly berthed,
but not certain and didn't see an official value

What's happening with HTV-X1? Is it still connected to the ISS?

If we can see it at:
https://www.nasa.gov/international-space-station/space-station-visiting-vehicles/
The answer is yes! What next?
