We present several examples of whistler mode chorus observations from the equatorial source
region made by the THEMIS (Time History of Events and Macroscale Interactions during Substorms)
spacecraft. Electromagnetic analysis of the Poynting vector reveals two groups of oppositely
propagating chorus elements, along and against the direction of the ambient magnetic field.
Additionally, there is a shift in frequency visible between both groups. We interpret these features in
the frame of the Backward Wave Oscillator (BWO) model as a possible generation mechanism for
chorus emission.
