New Evidence for Equatorially Trapped Thermal Plasma During Early Post-Storm RecoveryAlmost 20 years ago Olsen et al. [1987] reported Dynamics Explorer 1 Retarding Ion Mass Spectrometer observations of equatorially trapped, cold ions in the vicinity of the plasmapause. In that study the trapped population corresponded to a local minimum in density at the magnetic equator. During that time period observations were uncovered of a local maximum in plasma density at the equator. Until IMAGE there has been no good opportunity to experimentally revisit this topic, however until now no direct evidence of a relevant equatorial process has been recognized near the plasmapause during early recovery conditions. It appears that evidence has now been found in both the Extreme Ultraviolet Imager and Radio Plasma Imager observations. The observations, conditions, and properties of what appears to be an equatorially trapped and enhanced density near the magnetic equator will be presented and discussed.
