In a communication to the Minor Planet Center on Mar. 3, R. Kracht
suggested that, on the basis of the apparent motion, there was some loose
association between the above comet C/1999 M3 and C/2000 O3 (cf. MPEC
2000-Q09), despite the evident difference in the usual orbital elements.
Nevertheless, it can be noted that the perihelion directions are L = 103.9,
B = +11.4 (degrees, J2000.0) for C/1999 M3 and L = 100.6, B = +10.8 for
C/2000 O3. On Mar. 4, Kracht wrote that, again despite differences in the
usual orbital elements, the perihelion direction for C/2000 O3 is close to
the average value, L = 102.6, B = +9.7, for the four clear members of the
Marsden group (cf. IAUC 4832). A more extended relationship among these
comets is therefore suggested.
