    Hello everyone,
    (all times in UTC)
    
    As it looks like Endeavour will finally get off the ground for the STS-127
    mission, here are some visibility predictions.
    
    For our European friends, unfortunately they won't be able to see a pass of
    the shuttle with its jettisoned fuel tank because both will be in shadow at
    the time of their pass. It should cross northern France at 23:35 and shadow
    entry should be at around 23:31.
    
    I've corrected the TLE given by NASA for the coasting arc after MECO on its
    Shuttle Trajectory Data page and it should be something like this :
    STS-127 MECO
    1 00127U 09037A   09193.97578703  .01000000  00000-0  70000-3 0    16
    2 00127  51.6379 174.7098 0132826 348.8326  72.1224 16.48533989    10
    
    For Europe, the first visible passes will be on Monday evening. The
    following elset should give good results for predicting local passes :
    STS-127 NC2
    1 00127U          09194.71386507  .00020000  00000-0  70000-3 0  9048
    2 00127  51.6380 170.7619 0046101 145.6919 214.7243 15.85847420   134
    
    For North America, the launch will be in daylight. After the first orbit, it
    should be visible for the northeasternmost part the US and in Quebec and the
    maritime provinces in Canada. Predicted pass for Quebec is at 00:54. TLE to
    use is :
    STS-127 OMS-2
    1 00127U          09194.02647889  .00020000  00000-0  70000-3 0  9023
    2 00127  51.6379 174.4226 0055922 341.6503  18.2671 16.30239206    23
    
    For the rest of the US, early evening passes will be visible and can be
    predicted using this TLE valid after 02:46
    STS-127 NC1
    1 00127U          09194.14991408  .00020000  00000-0  70000-3 0  9036
    2 00127  51.6417 173.7444 0084750 161.5000 198.9289 15.95868349    41
    
    For the southern hemisphere, there will be morning passes starting in New
    Zealand (Hi Robert!) at around 18:03 on July 13 (Tuesday morning in NZ). The
    NC2 elset shown above should be used.
    
    Happy observing !
