Fig. 2From: Space-to-space very low frequency radio transmission in the magnetosphere using the DSX and Arase satellitesSpatial configuration of DSX–Arase transmission event at A 05:57:48 UT, closest approach of Arase to the DSX magnetic field line, and B 06:00:42 UT, closest spatial approach of Arase and DSX. DSX location and direction of motion are indicated by the black dot and dotted arrow, respectively, and the same for Arase are indicated in red. Geomagnetic field lines are shown as black dashed lines. Direct VLF ray paths are shown in blueBack to article page
