Fig. 3: Comparison of INTEGRAL gamma-ray and CSES electric field measurements.
From: Evidence of an upper ionospheric electric field perturbation correlated with a gamma ray burst
Comparison between the SPI gamma-ray flux (panel a) and the ionospheric electric field observed by the CSES satellite (panel b), after the subtraction of the vs × B induced electric field (vs and B are the spacecraft speed and the local magnetic field, respectively). The blue-shaded region corresponds to the CSES flight over the Auroral Region. The CSES electric field observations were measured at an altitude of 507 km.
