"Pseudo-MPEC" for ZTF0EWD = C1A3AQ1 = 67040 obj

Created 2020 Sep 17 11:54:07 UT using Find_Orb

Click here for an explanation of pseudo-MPECs

This object is in an orbit resembling that for 1967-040F. It's quite small, and is probably one of the untracked bits 1967-040C, D, or E. Jonathan McDowell suggests it could also be the (uncatalogued) spin interstage between Velas 4A and 4B (1967-040A and 1967-040B), a small bit of hardware roughly 30 cm in diameter and 10 cm high, also in this orbit.

TLEs are available for this object (and for most of the other objects listed on these pages.)
