    In fact, the satbase that was available at the time this is said to have 
    been downloaded had in excess of 550 objects with "Today's Epoch Date" 
    and not just the 27 listed (why?) above.
    
    At least this gives me the opportunity to apologise for the fact that no 
    updates to satbase will be possible between September 18 and 22.
