The relativistic electron flux and the Pc5 power. (top) The relativistic electron flux (>600 keV) at geosynchronous orbit (magenta) and the geomagnetic power at TNB (black). (bottom) The cross-correlation of the E > 600 keV (solid) and E > 2 MeV (dashed) electron flux with the Pc5 power at TNB (black), AQU (red), and GOES 12 (green) during 2007 to 2008, together with the 95% confidence levels (dashed, gray lines).
