    Thanks for the launch data.
    
    I must be doing something wrong.  When I use this for the Skymap TRJ file:
    
    61.34 37.78  -75.28 34.68
    133.37 37.50 -74.06 129.53
    135.47 37.49 -74.01 132.07
    208.87 36.78 -71.16 220.11
    472.04 32.26 -57.97 415.92
    540.24 30.74 -54.23 419.26
    
    The track loops Right to LEFT (SE to ESE) over the planets clustered the SE
    at a maximum altitude of 20 deg above the horizon.  Does this sound right? 
    
    I would expect the track to drift to the south.

    Subject: Minotaur-1 Mission Events
    
    Björn Gimle had written to me to request that I post the altitudes, lats and
    
    longs, 
    (or coordinates that can be converted to those), for Monday's Minotaur I 
    launch, then
    other observation locations can benefit (using SkyMap trajectory mode).
    
    Here is some data which may be of some help:
    
    Event                      MET       Lat.        Long.       Alt.
    --------                      -------       -------      --------       
    -------
    S1 SEP/S2 IGN       61.34      37.78     -75.28      34.68
    S2 SEP                 133.37      37.50     -74.06    129.53
    S3 IGN                  135.47      37.49     -74.01     132.07
    S3 BURNOUT        208.87      36.78     -71.16     220.11
    S4 IGN                  472.04      32.26     -57.97     415.92
    S4 BURNOUT        540.24      30.74     -54.23     419.26
    
    MET = Mission Elapsed Time in seconds
    Alt. = Altitude in kilometers
    
    At the Stage 3 ignition, the altitude will be equal to 82.05 statute miles.
    This means that at that point, the altitude of the rocket should enable
    it to be seen for a radius of 868.84 statute miles from the point of 
    S3 ignition.  This would -- in theory -- allow visibility of the rocket from
    
    southern Maine south to northeastern Florida and as far west as 
    eastern Kentucky.
    
    My thanks again to Ralph McConahy for providing the data concerning the 
    Major Mission Events for the Minotaur TacSat-2 launch.
