Observer details:
249 SOHO. SOHO-LASCO coronagraph C2. Comet detections by R. Kracht,
measurements by K. Battams, reductions by B. G. Marsden. The observations
of C/2001 D1 here include complete replacements for the positions given on
MPEC 2002-O27 and MPC 46184-46185; Kracht has now also recognized a
separate post-perihelic set of observations.

Kracht has pointed out that these comets, as well as C/2004 X7 (MPEC
2005-A40), are evidently related. Attempts by Kracht, as well as by the
undersigned, actually to link pairs (or all three) of these comets (assuming
P = 3.8 or 7.6 years) have not been entirely successful.
