Note: The latest elset has this 18 sec late against yesterday's
prediction but only 0.3 sec late against a prediction I posted on my
Decay Watch page five hours ago. I show this decaying after the
northbound equator crossing at the end of the final SatEvo-predicted
orbit, above. This puts it over N China. If it stays in orbit, there is
a southbound pass across Canada and the USA that takes it close to
Thunder Bay, Ontario, at 08:27 UTC, and almost due southwards to New
Orleans at 08:31. SpaceCom's latest estimate has it lasting well into
the next orbit that would carry it southwards from near Calgary,
Alberta, at 09:53 to Phoenix, AZ, at 09:58.
