Relating Solar Source Magnetic Connectivity to SEP properties seen at 1 AUA.J. Coyner, D, Alexander, and M.I. Desai

  • We investigate the effects of solar magnetic configuration (determined with PFSS extrapolations) on observed (Fe/O) ratios for 42 events including January 20, 2005.

  • Comparisons with Fe/O made at ULEIS energies (0.32-0.45 MeV/Nuc)

  • January 20, 2005 specifically shows significant open field with the extrapolation.

    • Less open field magnetic flux than the other campaign events with open field.

  • We see correlations in the open field event data between Fe/O and open magnetic flux influenced by the high Fe/O ratio events

  • Future plans include magnetic flux comparisons with ratios at SIS energies as well
