Hi folks,

This object has nominal H=25.3, and looks as if it will
come to within about 100 000 km (a quarter of the distance to
the moon), sometime in the next few days (nominally March
3.7, plus or minus a few days). It may get up to mag 11
or 12. (*)

I think the NEOCP ephemeris may be a bit off for this object,
as sometimes happens with very near-earth objects. The nominal
orbit shows an approach much earlier than I'd expect. It would
be an excellent thing if someone got some astrometry for it
(current arc is 2.6 hours long, last observation at 15:01
UT, five hours ago as I write this).

(*) For cases of this sort, I really need better tools, such
as statistical ranging... long on my 'to do' list. Since I
don't have that, I can't rule out a well-hidden second solution.
But I'm sure enough of the above comments to ask for data.
