My final prediction for the decay of #25903, the Foton 12 Soyuz rocket,
shows an increased possibility that the event may be visible across
parts of Canada and the USA within the next hour. I currently compute
re-entry at September 25 03:02 UTC near the Washington-Montana border,
though the uncertainty is some 40 minutes.

occurs NW of Vancouver at 02:57 UTC, and it may not even make it as
far as this. If it does survive, it passes NE of Vancouver at 03:00,
then across the W USA from Spokane, Washington, at 03:01 to San Antonio,
Texas, at 03:07.
