    Bram Dorreman, Marco Langbroek, Tim Luton, and I, contributed observations used to produce the following elements:
    
    NOSS 3-5 (A)                                           1014 X 1207 km

    NOSS 3-5 (B)                                           1015 X 1207 km
    1 79937U 11014B   11109.03548857  .00000000  00000-0  00000-0 0    07
    2 79937  63.4167 342.7331 0128413 180.9847 179.0943 13.39251023    05
    Arc 20110415.23-0419.07 WRMS resid 0.029 totl 0.023 xtrk
    
    For 11014A, only the inclination is a fixed estimate. Since there are fewer obs of 11014B, I used the elements of
    11014A, adjusting only the epoch, mean anomaly and mean motion. The longer observational arc of 11014B is due to the
    inclusion of a synthetic observation of 11014A, near its first ascending node, when both objects should still have been
    close together.
    
    11014B has yet to be publicly catalogued, but if the procedure of all four past NOSS 3 launches is followed, within a
    few days it will be falsely catalogued as a piece of debris of 11014A.
    
    A welcome feature of this launch was the prompt de-orbit of Atlas V-411's second stage, within a couple of hours after
    payload deployment. This seems to have become USAF standard operating procedure for LEO EELV missions. I believe the
    following list is complete; final column lists the place of disposal.
