    Since it is not attitude controlled like Iridium, that is no good analogy.
    
    Mathematically, the possible flash locations could be predicted like we do
    for Superbird A, ETS-6 and a few more satellites.
    
    But practically it is impossible, because we would need hundreds of accurate
    flash positions to determine the axis, and it would only be valid for a
    short time, because of eddy currents and atmospheric interaction at their
    low orbital heights.
