Joe,

I used the AMSAT web site to check your numbers (
http://www.amsat.org/amsat-new/tools/predict/).  Enter the coordinates you
gave and choose "next 30 passes" or so to look ahead into the future.

The first passes of the day seem to be within +- 1 minute of your
predictions for 50, 51, 27, and 16.  ISS is about 4 minutes off, so you
might want to update your keps for that one.

I didn't go beyond the first passes of June 15.  As the textbooks say, that
is an exercise left to the reader.
