Since my posting earlier this UK evening, SpaceCom/OIG have released a
few more widely-spaced elsets for the OPS 2849 deb which, despite its
name, may be a visible decayer.

Note: I place decay at a northbound equator crossing SE of India but the
near-circular highly-inclined orbit and the (still) large uncertainty
in time mean that it could fall almost anywhere.
