    Congratulations to Daniel Deak and his friend on spotting #26085, the
    Globalstar Delta 2 rocket at 08:21 UTC, particularly when it was
    (indeed) running well ahead of my prediction. In fact, the latest
    elset...

    ... has it 109 sec early against the prediction, and the decay is
    certain to be much earlier than I estimated. This means that Dan's obs
    was even closer to decay than he thought, but it also means that any
    chance of seeing it again tomorrow is gone.
    
    SpaceCom's current prediction is for decay while northbound at May 14
    19:41 +-4h near 20.1 S, 31.4 E, which is over E Zimbabwe, Africa.
    However, I guesstimate that this will decay a little more than one orbit
    later in the vicinity of a northbound equator crossing near 25.7 E at
    May 14 21:11 +-2h.
