The following fragment may decay after sunset Thu.Jul.20 at
Southern U.S. latitudes, but is only .0170 sq.m. according to
NASA's ssr06orb, just released :
Nimbus 4 Agena fragment

This rocket will decay about July 27:

#22808 is visible, at least from Canada and
mid-northern Europe, until decay.
ndot2 has not kept a constant difference compared to the recently
decayed EORSATS, which would indicate that the orbit correction system
is working at maximumum efficiency. If this were true, it would decay
within a week.
Instead, ndot2 has been about 1/3 of what #22709 had in corresponding
orbits, indicating a similar relation in area/mass ! If this is true,
it could last about three weeks, and become visible over larger areas.
