[neo_followup] TMG0047 = possible artsat

[Bill Gray]

Hello all,

    This object has two solutions.  One would be a NEO.  The
other would be an artsat,  in a fairly persuasive one-day
orbit.

    By default,  Find_Orb gets the distant,  NEO orbit.  To
get the artsat orbit,  run Find_Orb with the observations
currently on NEOCP,  and set a distance to the object of
70000 km.  (You can hit 'r',  then enter 70000km.)  Do a
few Herget steps,  then a few full steps (hit 'h' a few
times,  then hit 'f' a few times).  You should see elements
that look like this :

Orbital elements:  TMG0047

    and should be able to generate ephemerides suited to your
location.

    The uncertainties for this object are still manageable,
though some larger fields of view may be needed in a few
hours.
