    Hi All,
    I have been following the discussion on the transfer of TLE publication 
    from OIG to
    Obviously, we are concerned how this will affect Heavens-Above and the 
    user agreement seems to prohibit our publication of visibility 
    predictions using the TLEs from Space-Track. Until now, we have obtained 
    our TLEs from a number of sources, but primarily from OIG. We already 
    have an account at Space-Track, and will be updating our scripts to 
    obtain TLEs from their site  in the near future.
    Our policy will be to apply for permission to publish predictions based 
    on TLEs downloaded from Space-Track, and until permission is either 
    given or explicitly refused, we will continue to publish. In the event 
    of a refusal, we will have to look for other sources for our elements.
