LARGE-SCALE INTERPLANETARY MAGNETIC-FIELD CONFIGURATION REVEALED BY SOLAR RADIO-BURSTS

An instantaneous view of the interplanetary extension of the solar magnetic field is provided here by measurements from a space platform at high ecliptic latitudes of the trajectories of individual type III solar radio bursts. The Ulysses spacecraft provides this unique vantage point with an orbit taking it far from the ecliptic plane. The Ulysses radio measurements illustrate the capability of detecting and tracking coronal disturbances as they propagate through the interplanetary medium.
