[Neocp_artsats] C1NHY61 = probable Vela

    The elements are not good enough to allow for an ID,  but there
isn't much that would be in this orbit that isn't a Vela.  On
the other hand,  it's hard to see how this has gone unobserved
for so long.  (The answer may lie in the fact that at least at
present,  it's not a great northern hemisphere target.)

    If it's recovered,  I should have an orbit good enough to
run back and identify it.  Of the twelve Velas,  we have data
for eight,  TLEs of doubtful quality for two,  and decades-old
TLEs for two.  I am reasonably sure that if we get more data,
it can be shown to be one of the last four.
