Observations of three solar radio bursts, obtained with the Very Large Array of the National Radio Astronomy Observatory at 6 cm wavelength, have been combined with meter observationss from the Mark III Nancay Radioheliograph. There is a good correlation between solar activity observed at the two wavelength domains. A small change by about 10'' in the centimetric burst location corresponds to a large change, by about 0.5 R/sub sun/, in the related metric type III burst location. This indicates discrete injection/acceleration regions and the presence of very divergent magnetic fields.
