On the minimum fluxes of low-energy ions (0.5 MeV/nuc – 8 MeV/nuc) at high heliospheric latitudes

The quiet-time fluxes of ions from 0.5 MeV/nuc to 7 MeV/nuc (for oxygen) have been studied for the time period between mid-1993 through the first 104 days of 1994. During this time period Ulysses was below the heliographic current sheet. We find that at the quietest times, the ion population is domi...

Description
Summary:The quiet-time fluxes of ions from 0.5 MeV/nuc to 7 MeV/nuc (for oxygen) have been studied for the time period between mid-1993 through the first 104 days of 1994. During this time period Ulysses was below the heliographic current sheet. We find that at the quietest times, the ion population is dominated by the ACR component. For more active times, but still avoiding the most active time periods, the population below 3 MeV/nuc contains a CIR component as well as ACR ions.
