I think you did.  Iridium 9 NORAD #24839 COSPAR 97030D
was at AZ 138 EL 49 at 01:40 UTC 10-Sept-97 (UTC) or
9-Sept-97 (local) from Dallas, Texas.  Others, including myself,
have seen Iridium flares in that area of sky in evenings.

I use STS Plus.  What I did is change the date in my computer
dos, then change the Primary Location in the STS Plus.  Then
I would run the Pass Predictions part of the program sampling
an Iridium in each of the 5 Iridium groups to get close.  Actually
the first group was close so that's as far as I went.  Iridium 9 looks
like it matches with these TLE's obtained from OIG via VSOHP.

I suspect that others use more direct methods to determine unknowns
but this is the only way I know.  I must have an idea as to what object
it was and then make some trial pass predictions.
