    I failed to find either object last night.
    
    I have reviewed the information for Milstar 4 and 5 and I have come to
    the conclusion that the RA of Node is always supposed to be 309.
    
    So I have new guesses for the elsets:
    
    Pred Mil 6
    1 99991U          03098.83819000  .00000000  00000-0  00000-0 0    11
    2 99991   4.5000 309.0000 0001000   0.0000  98.2000  1.00274000    11
    Pred Mil 6 Cr
    1 99992U          03098.83819000  .00000000  00000-0  00000-0 0    11
    2 99992   5.2000 349.0000 0001000   0.0000  58.3000  1.00274000    11
    
    However, these elsets have orbital insertion at longitude 91 west.
    Milstar 5 was at 94.3 west.  The nominal information for Milstar 4
    said 99.5 west.  So there is still an uncertainty of up to 30 minutes
    even if this fundamental node value is correct.
