•New radio window in the decameter-hectometric (DH) wavelength
domain due to WAVES experiment on
Wind (Bougeret et al. 1995)
•All are CME related: Early phase of IP shocks
•Shock-accelerated
(SA) electrons produce complex type
III bursts (Reiner & Kaiser, 1999)
•Associated CMEs are faster and wider (Gopalswamy et al. 2000-GRL, 2001-JGR)
•Good Indicators of geoeffective CMEs
•CME interaction discovered (Gopalswamy et al. 2001, ApJL, 548, L91)
•No imaging: Need SIRA and LOFAR for studying these radio burst sources
