    The GEO insertion burn is some 240 seconds long. Anybody care to guess
    the longitude and whether its over the nightside of the Earth. Should be an interesting sight if it
    was. Also a second short event for CCAM burn. 
    Then we have a delta 2nd stage in near GEO. Brighter or fainter than a Centaur?
