Observer details:
249 SOHO. SOHO-LASCO coronagraphs C3 and C2. Comet detections by R. Kracht
(1999) and S. Hoenig (2002), measurements by D. Hammer, reduction by
B. G. Marsden.

C/1999 P6, 1999 P8 and 1999 P9 belong to the Marsden group, C/1999 P7
to the Meyer group and C/2002 F2 to the Kreutz group.
R. Kracht points out that, like C/1999 N6 (cf. MPEC 2002-F03), C/2001 Q7
(cf. MPEC 2001-R36) does not have a unique orbit solution, an alternative
low-i solution being:
Comet T q e Peri. Node Incl. C
CK01Q070 2001 Aug. 21.80 0.0445 1.0 54.77 43.95 13.28 X
He suggests that, with C/1999 M3 and perhaps C/2000 O3, these comets form part
of the extended Marsden population (i.e., having the same longitude and
latitude of perihelion). Indeed, we could say that these four comets belong to
the Kracht group.
