    Gerhard,
    For an observer much nearer the southern or northern apex of the orbit
    there would be more passes between the first 2 you predict and the last 2.
    You and I (-34.9 )are not far enough south to get the effect Kevin mentions
    on a 51.6 degree inclination orbit at 350km above the earth's surface.
    A higher orbit and/or lower inclination would give the effect.
    A selection of the Northern Hem. Observers on this list are in a better
    position relative to the apex.
