The large solar event on November 6, 1997, was enriched in heavy elements (Fe/O~1) with very hard energy spectra (power law index of -2). There was also a large enrichment in heavier isotopes, suggesting unusually strong charge to mass (Q/M) fractionation (~(Q/M)-7). Assuming that the fractionation is dominated by Q/M and first ionization potential (FIP) related processes, we have inferred the charge states of twelve elements with energies of 12--60 MeV/nucleon. These results suggest a source temperature of 3--6¿106 K, significantly higher than deduced at lower energies. ¿ 1999 American Geophysical Union |
