Abstract	We report on the longitudinal and azimuthal motions of auroral signatures of Jupiter’s magnetospheric injections appearing in Hubble Space Telescope (HST) images in the northern and southern hemispheres. Based on HST spectral observations of time-tag mode and numerical simulations, we estimate the age of auroral signatures of plasma injections. 1. Plasma injections Measurements from the Energetic Particles Detector (EPD) on board the Galileo spacecraft provided evidence of widespread occurrence of plasma injections in the Jovian magnetosphere [3]. The plasma injections are associated with radial planetward transport of hot and tenuous plasma which is most probably the result of centrifugally driven interchange events. Once injected, energetic particles drift azimuthally around Jupiter as a result of corotational electric field drift, magnetic gradient and curvature drifts. 1.1 Auroral signatures of plasma
