| The existence of any hard X-ray directivity from solar flares using data collected by the Reuven Rurality High Energy Solar Spectroscopic Imager (RHESSI) is investigated. The spatial distribution of flares, as well as the spectral index of the non-thermal emission regions of the flares, were studied to determine the existence of any directivity. No conclusive evidence was found in the 25--100 key energy range. |
