Multi-spacecraft radio observations trace the heliospheric magnetic field

Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III solar radio bursts. With multiple spacecraft now in orbit around the sun, we are in a unique position of observing the propagation of radio emission through the heliosphere from multiple vantage points.

With several space vessels now orbiting the sun, we are in a unique position to observe the spread of solar radiation [...]
