K. Battams has suggested the identity of the Marsden-group comet
C/2007 Y4 with C/2002 R4 (cf. MPEC 2002-S35). The following linkage (all
the observations having been made with the C2 coronagraph), by the
undersigned, yields for the previous perihelion passage T = 1997 May 15.2 and
an approach within 0.063 AU of the earth on 1997 June 14.7.
