I, too, have so far failed to find a candidate among all the
recent/current decayers. An analysis using several of the final elsets
for #22386 leads me to estimate its decay at Nov 14 20:41 UTC +-2h. the
final published elset for this is:
C 2227 Zenit deb CB                              213 x 197 km
1 22386U 92093CB  99318.55641527  .11760532  37627-5  39114-2 0  7004
2 22386  70.7882 313.2761 0012373  60.4478 304.9140 16.25392044372709
My prediction for the final orbit:
C 2227 Zenit deb CB                              167 x 159 km
1 22386U 92093CB  99318.80071748  .65975851  26023+1  44981-2 0 97005
2 22386  70.7834 312.5526 0006592  59.9438 300.1216 16.41079407372741

The description does sound very like a re-entry, but I don't think it
was of a catalogued object, unless a secret one.
