When you repost an object being late or early - quote the Epoch
of the elset you used (or the full elset) - not all SeeSat-ters
use the same source at a given moment !

The Dummy Masses are in high stable orbits. OIG identifies the F object
as Debris, but SeeSat-L observers agree it is the rocket
(exchange the names for C/F):
