    I have produced an MS Excel spreadsheet to compute azimuth, elevation, R.A. and
    Dec, during space shuttle ascents on missions to ISS:
    
    http://satobs.org/seesat_ref/Shuttle/Shuttle_Ascent_Trajectory_to_ISS.xls
    
    To use, enter your observation site co-ordinates and the date and time of
    lift-off, in the specially labelled cells (those with red coloured font).
    
    The trajectory data was for STS-88, as posted here:
    
    http://satobs.org/seesat/Jun-2000/0308.html
    
    I believe that for any given launch, the look angles computed by my spreadsheet
    will be accurate to within about one degree during the first several minutes of
    flight, and progressively less accurate thereafter.
