    Yesterday morning, it came to light that the following was our last reliable AHEF 3 TLE to-date:
    
    1 39256U 13050A   13362.30780316  .00000000  00000-0  00000-0 0    00
    2 39256   4.8845 304.1814 0345112 179.9578 336.7311  0.99205949    00
    
    Subsequently issued TLEs with RAAN ~328 deg, identified as AEHF 3, are in fact of MUOS 2. Mike McCants promptly withdrew
    the misidentified TLE and issued one for MUOS 2, based on new observations by Scott Tilley:
    
    1 39206U 13036A   14017.86278043 0.00000000  00000-0  00000-0 0    07
    2 39206   4.9473 328.0425 0056990 359.2826   0.4614  1.00270000    02
    
    The error arose because the orbits are similar in inclination and MUOS 2 happened to show up close to where the rapidly
    manoeuvring AEHF 3 was expected. The significant difference in RAAN was a strong clue to the mistaken ID.
