Possible problem with IridFlar program?

I have had success with the excellent predictions of the IridFlar program.  I
believe I have the latest version (dated 10/24).  I was excited to see a
flare coming up on Saturday night, but when I compared the prediction to the
output of SatSpy 2.0 and Quicksat, there was a substantial discrepancy.

Quicksat agrees with Satspy in predicting that Iridium 21 will be well out of
range at flare time.  Could someone point me in the right direction?  ( I am
VERY new at this! )  Have I made an error, or is there another explanation
for the discrepancy?

Data follows.        Thanks,   Gregory May
