    The launch time has been announced: 2005 Apr 30 at 00:50 UTC - quite a bit
    earlier than I had guessed.
    
    The result will be evening and morning visibility for much of the N. Hemisphere
    (all night north of the mid-latitudes). Unfortunately, the S. hemisphere will
    have a marginal evening visibility window, for the Lacrosse orbits only.
    
    The early launch should result in illumination of much of the ascent, so (time
    permitting) I will cobble together some trajectory information for the benefit
    of folks along the east coast of N. America.
    
    Here are elements for the 00:50 UTC lift-off:
