97072.11 would be 2:38UT.  Watch out Houston!

My numerical integration comes up with a slightly later time.

But the uncertainty is still quite large.

Here is the latest elset from OIG and it is only a couple of seconds
later than Alan's prediction.

1 23677U 95052B   97071.84063624  .07189284 -13221-5  97521-4 0  6037
2 23677  82.8948 299.6080 0019129 290.6809  69.2454 16.47793824 81051

But it has a still smaller than predicted drag term and mean motion,
so maybe the last of the 3 passes is not out of the question.
