Although the orbits computed for the SOHO comets that are members of
sungrazing groups other than Kreutz have hitherto necessarily been assumed to
be parabolic, the low orbital inclinations and the indicated associations with
meteor streams suggest that the members of the Marsden and Kracht groups, at
least, are of short period (which still means that e is no smaller than
0.98). If so, it might now be the case that individual members can be
recognized at more than one perihelion passage. Furthermore, the implied
success in having at least one member survive perihelion passage would provide
an obvious mechanism for the continued maintenance of these comet groups.
It is eminently possible that C/2004 V9 is in fact identical with
C/1999 J6 (cf. MPEC 2000-F30). To demonstrate this, the following represents
a tentative linkage of the observations. Since there is a well-known
inconsistency between the C3 and C2 observations, only the latter (i.e.,
those of the 1999 comet made on May 11.46257 UT and earlier and those of the
2004 comet on Nov. 8.35423 and earlier) have been used, the resulting
residuals being very comparable to those of the individual parabolic
solutions. It should also be noted that the object would have passed only
0.0091 AU from the moon and 0.0087 AU from the earth on 1999 June 12.22 and
12.31 UT, respectively:

Earlier computations, by both the undersigned and P. Chodas, Jet Propulsion
Laboratory, had suggested linkages among C2 observations of Kracht Group
comets, namely, the possibility that C/1999 M3 (MPEC 2002-E18) = C/2004 L10
(MPEC 2004-O05) and that C/1999 N6 (MPEC 2002-F03) = C/2004 J4 or C/2004 J18
(MPEC 2004-M71, 2004-N05).
