Abstract
The 1991 November 15 X1.5 flare was a well observed solar event. Comprehensive
data from ground-based observatories and the Yohkoh spacecraft provide the basi
s for a contextual interpretation of gamma-ray spectra from the Compton Observa
tory. In particular, spectral, spatial, and temporal data at several energies o
r wavelengths are necessary to understand the particle dynamics and the acceler
ation mechanism(s) within this flare. X-ray images, radio, Ca XIX data and magn
etograms provide morphological information on the acceleration region, while ga
mma-ray spectral data provide information on the photon energy spectra. Further
more, time profiles in hard X-rays and gamma-rays provide valuable information
on temporal characteristics of the energetic particles. We report the results o
f our analysis of the evolution of this flares as a function of energy (50 keV
- 10 MeV). These results, together with those from Yohkoh (14 - 100 keV) may as
sist in identifying and understanding the acceleration mechanisms(s) taking pla
ce in this event.
