Data from an example event where MAVEN and MEX crossed the bow shock within 10 minutes of each other. The left side shows MAVEN data, and the panels show (a) the electron energy spectrogram, (b) the ion energy spectrogram, (c) the magnetic field, (d) the ion density, (e) the ion bulk velocity, and (f) the spacecraft position. The right plot shows MEX data, and the panels show (g) the electron energy spectrogram, (h) the ion energy spectrogram, (i) the proton density, (j) the proton velocity, and (k) the spacecraft position. The arrows above the two figures indicate the regions through which the spacecraft traveled. The vertical black line shows the manually chosen bow shock crossing. All data are given in the MSO coordinate system.
