Measurements at Jefferson Lab of the transverse asymmetry AT in few-GeV electron scattering from various nuclei at forward angles will be presented. The electron's spin is polarized transverse to its momentum. The asymmetry arises from the interference of one-photon and two-photon exchange and is a potentially important systematic for parity-violating electron scattering experiments. The nuclei measured are H, 2H, 4He, 12C, and 208Pb at corresponding kinematics (E, ?) (GeV, degrees) = (3.18, 6), (6.06, 13), (2.75, 6), (1.05, 5) and (1.05, 5). The asymmetries are a few parts per million (ppm) and will be compared to available theoretical calculations.
