The platform may have already decayed, perhaps around November 4.8 if
the above elset is correct.

I calculate that the rocket may decay at about November 6.6 +-0.4d.
My prediction from a fitted SatEvo evolution through its published
elsets:

It is poorly placed for most of us. It enters eclipse while moving
southbound near 41 deg S latitude at ~20h local time and leaves eclipse
northbound near 18 deg S at ~04:30 local.
