Figure 7From: Investigating the particle precipitation of a moving cusp aurora using simultaneous observations from the ground and spaceSchematics of the spatial relation between the plasma boundaries and the three auroral structures. The dotted line represents the DMSP F18 pass. Boundaries 2, 3, 4, and 5, which were determined from the DMSP data (Figure 4), are plotted as black dots on the line. Regions a, b, and c, which are indicated within the auroral region, are also based on the DMSP data (Figure 4).Back to article page
