    #24211 = 96- 44 D = Italsat 2 Spelda
    
    This kept quite close to the SatEvo prediction I posted yesterday, the
    final elset...
    Italsat 2 Spelda                                 348 x 117 km
    1 24211U 96044D   00153.45424917  .45825776 -34996-4  76048-3 0  2652
    2 24211   5.7566 146.9117 0175125 104.2087 257.8707 16.15342273 48151
    ... showing it running 23 sec early. I believe that the elset above is
    for the final equator crossing, with decay coming some distance beyond
    perigee on the rev at Jun 1 11:29 +-20m near 3.3 N, 130.7 W. This puts
    it  over the eastern Pacific, not the western Pacific as I stated
    yesterday.
    
    SpaceCom has yet to issue its post-decay notice, but the preceding one
    predicted decay for Jun 1 11:13 +-55m at 5.4 S, 160.1 E, earlier on its
    pass across the Pacific.
                ____________________________________________
    
    #26371 = 91- 15 K = Astra 1B Ariane 44LP deb
    
    The latest and possibly final elset for this is...
    Astra 1B Ariane 44LP deb K                       666 x 135 km
    1 26371U 91015K   00153.03449303  .14583796 -29849-4  11852-2 0   114
    2 26371   7.3214  50.9049 0391303 301.4207  55.0100 15.55599723 52741
    
    There is no updated prediction from SpaceCom, but I show this decaying
    at Jun  1 14:10 +-4h near 5.5 S, 104.8 W. Like #24211 a couple of hours
    earlier, I place this decay over the eastern Pacific.
