On the origin of pre-reversal enhancement of the zonal equatorial electric field
In November 2004, a large and variable interplanetary electric field (IEF) was felt in the SHOPSTORM_HIDDEN_PRODUCT reference frame of the Earth.This electric field penetrated to the magnetic equator and, when the Jicamarca Radio Observatory (JRO) was in the dusk sector, resulted in a reversal of the normal zonal component of the field.In turn, thi
