It seems likely that the Kracht-group comet C/2005 W4 is a return of
C/2000 O3 (cf. MPEC 2000-Q09), a suggestion made by S. Hoenig before the
observations above were available. The following orbital linkage utilizes
just the C2 observations (those from July 30.89596 onward in the case of
C/2000 O3); although only the first three C/2005 W4 observations were obtained
with C2, the residuals of the C3 observations are not systematically displaced.

Comet C/2005 W5 has not been satisfactorily linked to a Marsden-group
candidate at its previous perihelion passage, although potential fits to
the various 1999 members seem preferable to those involving the comets of
Feb. 2000 (cf. MPEC 2005-W07).
