G'day Lee, this site
http://www.heavens-above.com/main.as...Alt=58&TZ=AEST
has info on iridium flares and there location in relation to where you are.
Once you have entered your location details, and click on iridium flares, you can see where they will be, click on the predicted time and it gives you a small map of the flare, and approx, distance and direction from you.
Hope this helps your addiction.....
