Note: The track just before the predicted re-entry carried this from
W->E across Canada from Vancouver at 13:29 UTC to the city of Quebec at
13:38. I locate the decay only 4 minutes further along the track, over
the NW Atlantic; SpaceCom places it near the following southbound
equator crossing just W of Africa.
