Simultaneous images of a flaring loop at two frequencies are used to modelthe magnetic structure of the loop and the energy distribution of the radiatingelectrons. The imaging data were obtained with the VLA at 5 and 15 GHz.Additional spectral data were provided by the OVRO Solar Array at severalfrequencies between 2 GHz and 15 GHz. At 15 GHz, the flare emission wasoptically thin and came from the footpoints of the flaring loop, while at 5 GHzthe loop itself was outlined. Most of the 5...
