Storms of Type III radio bursts at hectometer and kilometer wavelengths last from 1 to 12 days and consist of thousands of bursts. It has been proposed that sometimes a storm stops suddenly at the time of a major solar event including a large coronal mass ejection (CME). We look for temporal correlations between Halo CMEs and Type III storms, including storm cessations using a database spanning 1500 days. In the next few years, higher time resolution radio emission data from the upcoming ground-based Long Wavelength Array (LWA) and higher time resolution and unique position data from the dual platform STEREO mission (SECCHI, SWAVES) in the optical and radio bands will become available. With these instruments, locations of Type III storm emission source regions and CME geometries will be better determined, which will help resolve physical relationships and emission dynamics of storm - CME interactions.
Basic research in solar radio astronomy at NRL is supported by NRL/ONR.
