The aim of this paper is to study the blow up behavior
of a radially symmetric solution $u$ of the semilinear
parabolic equation
$u_t - \Delta u = |u|^{p-1} u, \quad x\in\Omega,\quad t\in [0,T]$,
$u(t,x)=0, x\in\partial\Omega, \quad t\in [0,T] $,
$u(0,x) =u_0(x),\quad x\in\Omega $,
around a blow up point other than its centre of symmetry.
We assume that $\Omega$ is a ball in $\mathbb R^N$ or
$\Omega =\mathbb R^N$, and $p>1$.
We show that $u$ behave as of a one-dimensional problem
was concerned, that is, the possible asymptotic behaviors
and final time profiles around an unfocused blow up point
are the ones corresponding to the case of dimesion
$N=1$.
