Type IV bursts are spikes of broad-band continuum emission that include a few distinct sub-types associated with different phenomena and different emission mechanisms. The first type to be defined was the moving Type IV burst, which requires imaging observations (i.e. interferometry) to detect. They are characterized by an outward-moving continuum source that is often preceded by a Type II burst in association with a coronal mass ejection (CME). The emission mechanism for Type IV bursts is generally attributed to gyrosynchrotron emission, plasma emission, or some combination of both that results from fast-moving electrons trapped within the magnetic fields of an erupting CME.
