We present a first look at the application of variational techniques for the
extraction of the electromagnetic properties of an excited nucleon system. In
particular, we include preliminary results for charge radii and magnetic
moments of the proton, its first even-parity excitation and the Δ+.Comment: 7 pages, 5 figures, presented at the 31st International Symposium on
