Using Ted Molczan's search elset for NROL-129 I started a planar
search at 20:36UTC. Four equally bright (~3rd mag) objects were seen
between 21:59 and 22:07UTC at high elevations (~80 deg). I have
labelled them 99567 through 99570, as it is not immediately clear
which object may connect to those seen by Russell Eberst on July 26.

Circular orbit fits for all four objects indicate a 575 km orbit at 54
deg inclination.

CSpOC lists 5 objects in orbit;  45873 through 45877 [20046A-E], with
45877/20046E being the Minotaur upper stage. Given the similarity in
brightness and orbital elements of the 4 objects seen, I would expect
these objects to be the payload, and that the upper stage is yet to be
found. However, time will tell.
