  We discuss the target and beam normal spin asymmetries in elastic
electron-nucleon scattering which depend on the imaginary part of two-photon
exchange processes between electron and nucleon. In particular, we estimate
these transverse spin asymmetries for beam energies below 2 GeV, where
thetwo-photon exchange process is dominated from the resonance contribution to
the doubly virtual Compton scattering tensor on the nucleon.
