There is probably a 3 to 6 hour window where it could be earlier or later depending on what position it is in when it first starts to get significant drag...
Is the chart being continuously updated?
(BTW, thanks for the chart. I had searched for one but not found it)
I got the track off a program called ‘Orbitron’. It was designed as freeware by a guy in Poland (of all places). Do a web search for it and you can download it yourself. It’s free and safe for your computer.
The program has a ‘Simulation mode’ where you can predict the future orbital tracks based off current data. That’s what I did by clicking through and advancing the time until tomorrow afternoon.
