  In this paper we study the dual charges of $\mathcal{N}=1$ supergravity in
asymptotically flat space-time. The action considered is the usual supergravity
action with a topological contribution. This is the Nieh-Yan term and the
magnetic term of the free Rarita-Schwinger field. Through methods of the
covariant phase space formalism we construct the charges conjugate to
supersymmetry, diffeomorphism and Lorentz transformations. The additional term
in the action will lead to new, non-vanishing contributions to these charges.
The magnetic diffeomorphism charges are equivalent to the ones previously found
for gravity, while the dual supersymmetric charges are new and do not appear
for the free Rarita-Schwinger field. The dual Lorentz charges serve to
regularize the previous two. We find that the asymptotic symmetry group for
supergravity can only include globally well-defined super-rotations.
