Electron fluxes at geostationary orbit measured by SOPA onboard (a) LANL-01 during 12–14 June 2005 storm and modeled by IMPTAM using the T96 magnetic field and Boyle et al. electric field models with Tsyganenko & Mukai (2003) boundary conditions at 10 R_E for (b) Maxwellian shape of the boundary distribution function, (c) kappa distribution function with k = 5 and (d) kappa distribution function with k = 1.5. Yellow and blue triangles indicate the local noon and midnight, respectively.
