    Using the revised Shuttle Trajectory Data found at:

    which assumes a 2:40 p.m. EDT launch time on Saturday, I have generated 
    a preliminary viewing schedule for the Shuttle Discovery over the Greater
    New York Area.  For the Saturday evening passes, I used the two-line mean
    element set #2:
    
    Jul 16 23:43:19.843 UTC
    1 99114U          05198.02036377  .00189937  00000-0  37621-3 0  9028
    2 99114  51.6475 108.6866 0027177 331.2562  28.7128 16.23809676    56
    
    For the Sunday evening passes, I used the two-line mean element set #6:
    
    Jul 16 23:43:19.843 UTC
    1 99114U          05198.88226355  .00189937  00000-0  37621-3 0  9052
    2 99114  51.6435 103.9230 0032695 338.5142  21.4672 16.22588515   194
    
    --------------------------------------------------------
    On Saturday, on orbit #5, Discovery should first appear at 8:56:20 p.m. EDT,
    10-degrees high in the NNW.  It should reach a maximum altitude of 24.5-
    degrees in the NNE at 8:58:10 p.m.  At this point its range distance from New 
    York
    will be 325 miles.  It will then descend to an altitude of 10-degrees, in the 
    E
    at 9:00 p.m.  Maximum illumination by sunlight of the orbiter is predicted to 
    be 90.8 percent.  This should be a very favorable pass!
    
    On Saturday, on orbit #6, Discovery should first appear at 10:28:55 p.m. EDT,
    10-degrees high in the W.  Just 17 seconds later, at 10:29:12 p.m., at an
    altitude of 11.6-degrees, in the WSW it will duck into the Earth's shadow and 
    be rendered invisible.  Maximum illumination by sunlight of the orbiter is 
    predicted to 
    be only 32.7 percent.  To say the least, this is a very unfavorable pass.
    
    -----------------------------------------------------------
    
    On Sunday, on orbit #21, Discovery should first appear at 8:34:56 p.m. EDT,
    10-degrees high in the NW.  It should reach a maximum altitude of 27.6-
    degrees in the NNE at 8:36:51 p.m.  At this point its range distance from New 
    York
    will be 302 miles.  It will then descend to an altitude of 10-degrees, in the 
    E
    at 8:38:46 p.m.  Maximum illumination by sunlight of the orbiter is predicted 
    to 
    be 94.1 percent.  
    
    NOTE: Sunset in New York City occurs at 8:24 p.m.  As such, evening (civil) 
    twilight will be in progress making the Shuttle difficult to see on this
    pass.   
    
    On Sunday, on orbit #22, Discovery should first appear at 10:07:46 p.m. EDT,
    10-degrees high in the W.  Just 56 seconds later, at 10:08:42 p.m., at an
    altitude of 13.4-degrees, in the SW it will duck into the Earth's shadow and 
    be rendered invisible.  Maximum illumination by sunlight of the orbiter is 
    predicted to 
    be 47.7 percent.  This is a rather unfavorable pass.
    
    STS-114 is scheduled to dock with the International Space Station on Monday.
