Despite your high-precision analysis of Earth-Sun and perigee relations, I see no consideration for the precession of the ISS orbit plane (-5.1 degrees/day). If the orbit (on the average) stays as low as it is now, I get (thanks, Ken Ernandes, for Vec2TLE!) the same siderial orientation of the orbit as on June 18,2003, but then the Sun would have been some +ten degrees in RA, so the E-S relation was almost identical on June 16,2003. It may make nice NB passes over Oman, Egypt, Greece, Spain-Italy during the transit!
