    If the ASAT weapon indeed had struck the satellite head on, the result would
    have been numerous pieces of debris (maybe up to 50%) traveling in the
    opposite direction, and some pieces would have fallen to the ground. No such
    pieces exist. That would have been like a head on collision between two
    cars, where the two wrecks and most debris normally come to rest about at
    the collision point.
    Given that all the debris pieces now travel in the same direction as the
    target and in about the same orbital plane, one can conclude that the ASAT
    weapon did strike from behind, with approximately a coplanar trajectory; and
    since most debris pieces have a higher orbit than the target satellite had
    originally, this indicates that the ASAT weapon struck from slightly below
    the satellite.
    To conclude: The ASAT weapon probably struck from behind and slightly below
    the target satellite.
