    The ascent trajectory and look angles are primarily of interest to observers
    near the east coast of North America, interested in observing the shuttle
    during its ascent to orbit. Since STS 130 will be launched at night, it will
    be readily visible, weather permitting. The entire ascent will occur within
    Earth's shadow.
    I have produced an MS Excel spreadsheet to compute azimuth, elevation, R.A.
    and Dec, and an indication whether the shuttle is in sunlight, or the umbra
    or penumbra of Earth's shadow, during STS 130's ascent to orbit on its
    mission to ISS:
    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 spreadsheet is set up for STS 130's scheduled launch on 2010 Feb 07 at
    09:39:47 UTC, as seen from Washington, D.C.
    I obtained the trajectory data from The CBS News Space Reporter's Handbook,
    by William Harwood:
    Scroll down to the SpaceCalc section, and see file for
    PC or for Mac.
