The Marsden-group comet C/2005 G2 presumably has an orbital period of
5-6 years, but it appears not to be a return of one of C/1999 P6, 1999 P8,
1999 P9 or 1999 U2 (MPEC 2002-F43, 1999-U29). The C2 data for C/2005 G2 do fit
well with the observations of C/1999 P8 (all being C2), but the current C3
data show a systematic R.A. departure increasing from 1 to 4 arcmin.
