    NROL-41 is scheduled for launch from VAFB on an Atlas V-501, on Sep 21, between 03:29 UTC and 04:28
    UTC.
    
    Assuming launch at the start of the window, I offer the following approximate elements:
    
    FIA Radar 1                                              622 X 636 km
    1 76000U          10264.14861112  .00000000  00000-0  00000-0 0    03
    2 76000 123.0000  86.2600 0010000   0.0000 137.2800 14.80000000    08
    
    I am fairly confident of the inclination, less so of the altitude, but this should be sufficient for
    prospective observers to begin to evaluate local visibility.
    
    The above elements reveal morning and evening visibility in the northern hemisphere, with the best
    visibility well south of 55 N.
