From 12 observations 2002 Feb. 4-5.
While the above comet, like some 95 percent of the comets discovered
by SOHO, is clearly a member of the Kreutz sungrazing group, it is rather
less appreciated that as many as 11 of the two dozen or so non-Kreutz comets
discovered by SOHO also seem to be interconnected. The close temporal pairs
C/2000 C2-2000 C5, C/2000 C3-2000 C4 and C/2000 Y6-2000 Y7 were remarked on
when these comets were announced (cf. MPEC 2000-C52, 2000-C53 and 2001-B08).
There is also the pair C/1999 J6 (MPEC 2000-F30) and C/1999 U2 (MPEC 1999-U29),
comets with i = 27 deg separated by more than five months. M. Meyer was the
first to point out the similarity between the orbits of C/1997 L2 (MPEC
1997-M06, MPC 35205) and C/2001 X8 (MPEC 2002-B01, MPC 44505), comets with
i = 72 deg separated by 4.5 years; it also appears that the poorly observed
comet C/2001 E1 can be associated with this pair, if the orbit with i = 107
deg on MPEC 2001-F52 is replaced by the one with i = 73 deg on MPC 44505.
