Comets C/2008 L6 and L7 appear to be members of the "Kracht 2" Group, and
R. Kracht suggests that they represent a return of comet C/2002 R5 (cf. MPEC
2002-S35). The 15-deg shift in the line of nodes actually supports the
likely correctness of this linkage, as it is consistent with the comet's
passage within 1.1 AU of Jupiter in Jan. 2007. The result of linking C/2002 R5
to C/2008 L6 (the brighter of the recent pair) is:
C/2002 R5 = 2008 L6 (SOHO)
