Sorry,  meant to post here as well :

Hello all,

    ISON has found an interesting NEO.  It shouldn't
be difficult to follow up (assuming it's done quickly;
it's fading),  except that the NEOCP doesn't use
earth/lunar perturbations.  Often,  that actually is
not a big problem.  Here,  it is.

    If you use Scout or Find_Orb ephemerides,  you'll
get a correct position,  one that ought to be right
to within about ten arcseconds.  Use the MPC position,
and you'll be off by about a quarter degree.

    Also,  note that the ISON astrometry doesn't specify
a magnitude band.  This object may be a bit fainter than
the ephemerides suggest.
