Hi Bob, do you know the object number by chance?
No, but this link shows that the higher probabilities or re-entry are between about 38 to 43 degree latitudes north and south.

Im not sure why those would be slightly higher. 43 degrees is its maximum excursion (matches its inclination)... Maybe its because as it passes over the equatorial bulge, it sees the higher drag and that will start the demise which will occur then 20 minutes later?

You can see the live track of Taengong to re-enter in the next 24 hours on http://www.heavens-above.com/
Just remember, as it suffers increased drag, it will speed up and be ahead of classic predictions.
But at least you can see when you are under the orbit as to whether it is worth going outside. I 'd go out several minutes before the prediction since we dont know how quickly they are updating the elements as it speeds up.
and even if it is daytime, you will see it if it comes in in your area...
