    Scott Campbell, Russell Eberst, Marco Langbroek, Tim Luton, Mike McCants, Pierre Neirinck, Greg
    Roberts, Patrick Schmeer, Peter Wakelin, Brad Young, and I, contributed observations used to
    determine one or more of the following element sets.

    Tim Luton's observations of AEHF 1 last night were complicated by their close proximity to the moon;
    his first point probably is reasonably accurate. Assuming my and Mike McCants' obs of Oct 15 UTC
    were on the same coasting arc as Tim's, then this is the approximate orbit:
    
    AEHF 1                                                4757 X 49973 km
    1 36868U 10039A   10290.00129173  .00000000  00000-0  00000-0 0    02
    2 36868  15.0433 296.5459 6700000 202.9331 101.7328  1.40080934    03
    Arc 20101015.13-1017.03 WRMS resid 0.010 totl 0.005 xtrk
    
    This represents quite a bit greater manoeuvre than my original estimate, and more than doubles my
    estimate of the HCT (Hall Current Thruster) burn time, to roughly 14 h.
    
    AEHF 1 r                                               234 X 49968 km
    1 36869U 10039B   10289.78974398  .00001686  00000-0  61790-3 0    00
    2 36869  21.3496 297.0328 7899644 205.9489  70.1221  1.55477855    04
