From: Electron Bernstein waves driven by electron crescents near the electron diffusion region

The black dashed curve shows the neutral line (defined where B\(_{{\rm{L}}}\) = 0), and the blue arrowed line denotes the MMS trajectory near the electron diffusion region. The large-amplitude electron Bernstein waves are observed on the magnetosheath side of the neutral line.
