Electron fluxes observed by EPT in October 2013 in Ch 5 (1–2.4 MeV). The magnetopause position is superposed on the upper panel (magenta solid line), as well as the last closed drift shell (LCDS) for October 2013 for K ∼ 0 (magenta dotted line) and the largest K that mirrors above 100 km everywhere around the orbit (magenta dashed line). The Dst index is also superposed (upper blue line).
