    I find it really curious to find three objects at nearly the same
    position (of course that's where he was observing) within 4 minutes and
    at roughly at the same magnitude, AND two of them at "exactly" the same
    speed of motion, all of them moving in the same direction (if PA is
    Position Angle)
    
    The middle object matches (16 sec.early):
    1 22517U 93010F   03042.91923586 -.00000055 +00000-0 +10000-3 0 05791
    2 22517 065.9319 002.1641 0014589 254.9964 104.8417 02.13409324077818
    
    P006CC and P006D3 appear to be the same object, close to 89-01E but at
    only 2/3 the speed, indicating a range of about 23000 km.
