as of a few minutes ago the reentry window for the defunct Chinese station has narrowed to +- 2.5 hours either side of ten after midnight UTC tonight.
That's 2:40 pm to 7:40 pm this afternoon/evening, MST (or PDT) (UTC-7).
The general trend over the past couple of days has been for the window to slide later, FWIW.
Looking at the ground track, the current projected middle of the window is way out over the Pacific. Alas for free local fireworks, the overall window comes nowhere near North America. Southern South America, much of Africa, Central and East Asia, yes. As for you Aussies, absent a major late change, no Skylab-Tiangong twofer. Oh well!
I notice that a bit less than one orbit after current projected mid-window, it'll be going right over the middle of China, which could make for a spectacular show for the people who paid for it.
