    The official launch time has been announced: 2007 June 14, at 15:18 UTC:
    
    http://www.spaceflightnow.com/atlas/av009/status.html
    
    Here are revised search elements for the lead object, at the first ascending
    node after orbital insertion:
    
    1 70001U          07165.70528159  .00000011  00000-0  20000-4 0    05
    2 70001  63.4420  45.4156 0107863 182.7436 177.3009 13.39714521    03
    
    The plane would be about 2 deg east of the NOSS 2-3 (96029C, D and E) plane;
    however, I note that the previous NOSS launch, from the same launch site, but
    using a different launch vehicle, targeted a plane 1 deg west of the NOSS 2-2
    (91076C, D and E) plane. I cannot exclude the possibility that the upcoming
    launch will steer into the same position relative the 96029 plane, in which
    case, the above RAAN (right-ascension of the ascending node) would be about 3
    deg too high. Of course, other planes are possible, so I recommend allowing for
    plus and minus several degrees uncertainty.
    
    Visibility windows remain substantially the same as described in my earlier
    message.
    
    In the event of a launch delay, the launch time will arrive 14 min/day earlier.
