Abstract
The magnetopause electron layer in the distant magnetotail is an annular region encircling the magnetopause in which bursts of tailward-streaming energetic (E > 200 keV) electrons are almost continually present. Sunward-streaming electron bursts with time scales and energy spectral indices similar to those of layer bursts are sometimes observed in interplanetary space upstream of the earth. Evidence is presented to show that the layer bursts and the interplanetary bursts have a common source. With the aid of a new coordinate system -- geocentric interplanetary medium (GIPM) coordinates -- appropriate for describing the access of energetic charged p[articles in the inner magnetosheath to a spacecraft located in interplanetary space, it is shown that the interplanetary bursts occur predominately on the sunward extension of the field lines associated with the magnetopause electron layer.
