Going through the unknowns in polar orbits seen this year,
observations of 5 unknowns can be linked to 2 objects, which may be
two 2 of the 4 Essaim objects [28494-28497/04049C-F]. Circular orbits
are below. The first candidate [99612/22503A] has an orbital altitude
and inclination which are somewhat different from the Essaim objects
617 to 635 km altitude, 98.2 to 98.3 deg inclination. Feel free to use
these orbits for performing planar scans, or for linking future
unknowns.

Regards,
    Cees
