Multi-spacecraft observations of Solar energetic electron events

Multiple spacecraft observations of solar energetic electrons provide important information on their source, acceleration and transport through the interplanetary medium. We have identified a few electron events observed by both the WIND 3-D Plasma and Energetic Particle Investigation (3DP) and the Lunar Prospector Electron Reflectometer (LP/ER) from January 1998 to July 1999. For these events, we estimated the timing back to the Sun through transport analysis of the onset/peak times of in situ electron fluxes at different energies. For three events with good enough statistics, we also obtained solar injection time profiles from best fits to the observed time profiles of electron fluxes, assuming triangular injections at the Sun with equal rise and fall times. We found a consistent timing for solar energetic electrons observed by the two spacecrafts. We will also present the results of searching the solar electron events observed by both the WIND/3DP and the Mars Global Surveyor Electron Reflectometer (MGS/ER).
