[Neocp_artsats] ZTF0K6x = unidentified junk, one-day orbit

Hello all,

    As above : I don't know what this is,  but the elements are clearly
geocentric.

    Currently on NEOCP,  we have ZTF0K7F and ZTF0K79,  which I suspect
are artsats with inclinations of about 15 and 20 degrees (very uncertain;
the arcs are four observations each,  less than two minutes).  ZTF0IvA
_might_ be junk,  but if so,  it's in a retrograde orbit,  which would
be quite unusual;  I think it was a "real" NEO.

    None of these objects links to one another,  nor do the elements
resemble those of recently found junk.
