Hi All,

I think someone may have already posted some of this information,
but below is a summary of discrepancies in the last two Sat Week
reports (#39 and #40).  Basically, they've posthumously decayed
4 objects that have "live" TLEs:

In any event, I'm not sure whether to delete these satellites
from my TLE lists, or continue carrying them.  --Rob
