The longitudes and latitudes of perihelion (deg, J2000.0) of these
orbits are L = 107.1, B = +12.0 and L = 96.0, B = +10.9, respectively.
C/1999 N5 is a clear member of the Marsden group and C/1999 N6 a likely
member of the more extended population (cf. MPEC 2002-E18, 2002-E25).
Possibly C/1999 N6 is quite closely associated with C/1999 M3 (though not
so much with C/2000 O3), but the orbit solution is not unique.
