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.
