    We use multicomponent measurements of the four Cluster spacecraft and a backward ray tracing simulation to estimate the location and size of the global source of whistler-mode chorus emissions in the magnetic equatorial plane. For the first time, analysis is made in a broad range of latitudes in both hemispheres along a single Cluster orbit. Our results show that for different time intervals, the sizes of the observed portions of the global chorus source region in the equatorial plane varied between 0.4-1.5 Earth radii. They were found at radial distances between 4.5 and 8.2 Earth radii during 2 hours of measurements. Therefore, the superposed minimum width of the global source region of whistler-mode chorus in the magnetic equatorial plane is approximately 4 Earth radii.
