    Note: The latest elset shows this running 3.1 min early against 
    yesterday's SatEvo prediction. For once, the current SatEvo prediction
    is in close agreement with that from SpaceCom. It shows this decaying
    in daylight northbound over the North Sea on a the last of these 
    SatEvo-predicted elsets. The track carries it over NW France at 12:07 
    UTC and onwards across Denmark to Stockholm, Sweden, at 12:11.
