         Obviously, because the short arcs of observations of these objects were
    obtained almost a year ago and the nominal orbital elements given above
    involve significant assumptions, the ephemerides given above are very
    uncertain.  It is perhaps not generally appreciated, however, that plots
    (and tabulations) of the current ephemeris uncertainties of single-opposition
    TNOs (and centaurs) are routinely included on the "Minor Planet & Comet
    Ephemeris" page ( http://cfa-www.harvard.edu/iau/MPEph/MPEph.html ) that the
    Minor Planet Center maintains on the World-Wide Web.  It is recommended
    that observers interested in attempting follow-up of a specific object should
    generally start from the nominal ephemeris at the center of the relevant plot
    and work steadily outward into the region plotted in green.  (Users should
    note that there can be a modest delay between the publication of an associated
    MPEC and the appearance of the corresponding ephemeris and uncertainties
    on the WWW.)
