 Abstract: Type III radio bursts are produced by beams of electrons that are accelerated at reconnection sites of solar flares. Although these coronal emissions are frequently detected by ground-based observatories, dedicated instruments in space are necessary to measure radio sources that are generated further in the interplanetary medium, due to the ionospheric cutoff at around 15 MHz. In this study, we present a statistical analysis of 20 type III radio bursts that were observed simultaneously by multiple spacecraft and associated with solar flares of magnitude M1 or larger. We used radio data that were recorded by Wind, STEREO-A, Parker Solar Probe, and Solar Orbiter. The multipoint observations allowed us to compare the locations of solar flares with the locations of radio sources. Our analysis revealed that radio bursts are statistically shifted eastward by 18 degrees, which could be explained by a poleward component of the local density gradient along open magnetic field lines.
