Figure 2From: Pc5 geomagnetic fluctuations in response to solar wind excitation and their relationship with relativistic electron fluxes in the outer radiation belt The correlation between magnetospheric and geomagnetic field fluctuation power. (a) The cross-correlation, averaged over 2006 to 2010, between the Pc5 power in the magnetosphere and at TNB (black) and AQU (red), together the 95% confidence levels (dashed, gray lines). (b) The dynamic correlation between simultaneous magnetospheric and ground geomagnetic fluctuation power at TNB (black) and AQU (red), and the SW speed (cyan). (c) A detail of 2007.Back to article page
