Leigh,

Below is the (brief format, English units) output I got from Iridflar.  
I hope I got lat and long right, and I just guessed at the altitude.  
Looks to me like it should have been there.  (By the way, GSOC is set 
to be pretty conservative about which Iridiums are considered reliable.  
So this may be something new on Ir 28.)  The verbose output predicted 
-8.2 and said the center line was about two miles east of the location 
that I used.
