Thanks for answering my post. I just noticed that DFW(where we live) is right under one of the ground tracks. We were right under Columbia when it broke apart and heard sonic booms as it re-entered. My husband and I were having coffee and a few minutes after we heard the booms, it broke on the news that it had blown up.

I did find this nifty little tracker just now:

It’s near Cuba right now.

Updated with newer data point derived from German radar. Looks like perigee is reaching down to 103 miles in altitude.

According to USSTRATCOM re-entry is going to be south of Chongking, China which is coming up pretty quick at 7:04PM PDT. I believe it is quite populated in that area.

Twitter users are reporting from various places they aren't getting any visuals on it so it is possible it is already down.
