A Pegasus fragment decaying tonight, two early Thursday (?) and
the SL-6 rocket #24801 have good visibilities.
The fragments are all listed as having RCS values of 0.032-0.039
sq.m. in June SSR, so except for flashes they may be around +10
at 1000 km.

24366 94029PT  Pegasus deb PT should be passing in sunlight tonight
at 21:41 UT over the British Isles (look up, Russell!) on its last
orbit ?

23:05 LST (#24395) 

#24801 appears to be sunlit for the entire orbit!

The Pegasus fragment elset bases for these were from 97214, so the
uncertainty can be expected to be +/- 3 min for these two, +/- 10 min
for #24366? Look for newer elsets on SeeSat-L or
