Per current 41.06 (June 2000) SSR:

60.6

The SSR orbital params for Jan 3, 1990 decayed item changed with the
June 30, 2000 report. Per my records and based on the following, 15786U
is a newly released elset possibly as a refound item.

Three

The remaining 21 orbiting have much higher orbits with the lowest being:

16547U   ELEKTRON 1 DEB   1964-006L   01/30/1964            1334   344

Well...at the very least they kept it (15786) within the family.  :-)
