•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
