    Hi Tom, using this TLE:
    1 25544U 98067A   03105.27461242  .00041100  00000-0  34010-3 0  9017
    2 25544  51.6329 336.2421 0006040  22.0682 338.0732 15.58140717 11196
    This is my prediction using the SKY.  The pass is as you see it (see screen
    shot) going from right to left entering the suns disk approximately at the
    2:30 postion, and exiting at the 10:30 position.  The pass lasts  of a
    second.  It looks like it will cut right through the top 1/4 of the Sun's
    disk...Be quick!
    Let me know how it went!
