     Concern has been expressed that observers are not continuing to make
follow-up observations of NEOs after the initial presentations of data in
these Circulars.  Indeed, particularly when there are many entries on the NEO
Confirmation Page, it can be difficult to decide when to transfer them from
the NEOCP to an MPEC announcement, for one also needs to ensure that genuine
and possibly dangerous NEOs on the NEOCP are recognized and do not get lost.
Post-MPEC follow-up observations are particularly desirable in a case like
this, where the large elongation from opposition leads to a clear double
solution.  Here the Aten-type solution has been selected.  It is at least as
likely that this object is significantly farther away and in a cometary orbit:
attention to the object's physical appearance is therefore also appropriate.
