During the 13 years these Circulars have been published, it has been
customary to issue one announcing the discovery of a transneptunian object
even when observations are available from only two consecutive nights.
Although the above orbits for 2006 QQ180 and 2006 SG369 are still quite
uncertain, with arcs of more than a month there is at least some chance
for recoveries at a future opposition, and this is frequently not the case for
objects with very short arcs. In the future, therefore, it is proposed not to
issue MPECs for new TNOs with observed arcs of less than one month.
Provisional designations will be supplied (as for main-belt objects observed
on more than one night), and generalized Vaisala orbits will be available for
ephemeris computation at http://cfa-www.harvard.edu/iau/MPEph/MPEph.html.
A separate webpage listing the designations of these candidate TNOs is in
preparation.
