Four flares that showed simple morphologies in the radio wavelength during the course of the type III bursts. The flare is imaged in EUV 195 Å by EIT. At the base of the loops there are the RHESSI 12–25 keV X-rays (red) integrated over the entire event. Higher in the corona there are the NRH 432 MHz (purple), 327 MHz (orange), and 237 MHz (blue) integrated over 10 s during the events where the start of this integration is indicated on each image. All contours are at 10% intervals starting from 70 percent.
