Observations of whistler–mode chorus made by the THEMIS spacecraft inside the equatorial chorus source region often exhibit the following peculiar features. Two groups of chorus elements are visible simultaneously which are approaching the spacecraft from two different directions: either along or against the direction of the ambient magnetic field. Furthermore, both groups are slightly shifted in frequency with respect to each other and elements are of different intensities. We interpret these features in the frame of the backward–wave oscillator theory by means of two exemplary events, yielding insight into the nonlinear generation mechanism and the specific source–observer geometry during the time of observation.
