We numerically investigate a particular type of spin solitons inside a trapped atomic spin-1 Bose-Einstein condensate (BEC) 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 $^{87}$Rb condensates. We discuss a rotating reference frame wherein the dynamics of the solitonic local spatial spin distribution become time independent.
