In situ measurements by STEREO A (red) and STEREO B (blue). Electron omni-directional (solid curves) intensities are shown for 45–65 keV (top panel), and for 65–105 keV (second panel). Intensities for the Sun (STEREO A orange-dotted, STEREO B gray-dotted) and Antisun (STEREO A orange-dashed, STEREO B gray-dashed) fields of view are also displayed for both spacecraft in these two panels. The solar wind velocity, plasma density and temperature are shown from the third to the fifth panels, respectively. Finally, the last three panels display the magnetic field strength and its direction (latitudinal and azimuthal angles in the RTN reference frame).
