We numerically investigate a particular type of spin soliton inside a trapped atomic spin-1 Bose-Einstein condensate with ferromagnetic interactions. Within the mean-field theory approximation, our study of the solitonic dynamics shows that the solitonic wave function, its center-of-mass motion, and the local spin evolutions are stable and are intimately related to the domain structures studied recently in spin-1 Rb-87 condensates. We discuss a rotating reference frame wherein the dynamics of the solitonic local spatial spin distribution becomes time independent.
