Hard X-rays Associated with CMEs
Abstract
In principle we can use hard X-ray bremsstrahlung (> few keV) to study the non-thermal tail of the electron distribution function in the solar corona. This approach is less sensitive than the techniques of radio astronomy, because of the low emissivity and low detection sensitivity for hard X-rays, but observations of major events are now possible; HESSI should greatly improve the breadth of such observations. These highly energetic flare events commonly are associated with CMEs. The view offered by such observations complements the radio techniques in interesting ways. This talk reviews data from several coronal hard X-ray events observed by the Yohkoh Hard X-ray Telescope and other instruments in the context of the radio observations.
