    I didn't see a reply on the magnitude question.
    One of my earliest space notes states that 1 m2 cross-section of a white 
    sphere is +6.4 at 1000 km full-phase.
    Assuming a golf ball is 25 times smaller in diameter makes that +13.5 
    There is a trade-off between the range and the phase of a satellite 
    pass, which I don't care to search for (I believe I posted it to 
    SeeSat-L), or compute again.
    Assuming the "best" range is 400 km, I would get +11.5
