A DYNAMIC-MODEL FOR INJECTION BOUNDARY OF RELATIVISTIC ELECTRONS IN THE EARTHS MAGNETOSPHERE

The position of the outer belt maximum for relativistic electrons inje cted into the magnetosphere during magnetic storms is shown to depend on the largest amplitude for D-st-variations for each storm. The depen dence is shown to be of the form: \D-st\(max) = 2.75 x 10(4)/L(max)(4) . The relationship of the relativistic electron injection boundary to such structural magnetospheric elements as the solar proton penetratio n boundary and the polar electrojet position, etc. are analysed.
