Decay watch: 2002 June 26

I had a problem in posting yesterday's decay watch note to SeeSat-L, so 
the final notice for the Agena D decay is repeated below. Since then 
SpaceCom has posted the first notices for three decayers, including the 
Soyuz rocket from the just-launched Progress M-46. A summary of the 
latest update to my Decay Watch page follows, but without my usual 
SatEvo predictions - I'm out of time as I leave for a few days away, so 
no further updates until July 1st (earliest), I'm afraid.
