Spatial and spectral characteristics of the X-ray sources in the 15 November 1991 solar flare
Abstract
Since the experiment turn-on in October 1991, many flares have been observed with instruments aboard the Yohkoh satellite. The flare on 15 November 1991 (2238 UT) is of particular interest because, in addition to Yohkoh, it was observed also by hard X-ray/gamma-ray spectrometers aboard Ulysses, Pioneer Venus Orbiter, and Compton Observatory/GRO spacecraft. We present preliminary results obtained from an analysis of the spatial and spectral parameters for the soft X-ray source and the spectrum and directivity of the hard X-ray source.
