Fig. 3From: Electron beam-associated symmetric electrostatic solitary waves on the separatrix of magnetic reconnection: multi-spacecraft analysisA series of typical cases of ESWs observed by C2 on the separatrix. a Parallel component of the electric field (E //) of C2 with the spin period of 18:35:28 to 18:35:32 UT (18:35:28.324 to 18:35:31.922 UT). b The zoomed-in waveform of E // between the two solid lines (600 ms from 18:35:28.653 UT) in Fig. 3a. An offset value (1.5 mV/m) in the amplitude is denoted by the horizontal solid lineBack to article page
