We consider similarities and differences in particle dropout features between energetic ion and suprathermal electron data in interplanetary particle events associated with impulsive flares at the Sun. Dropouts are thought to be caused by spacecraft encounters with magnetic field lines that are not connected to the particle source or, in a small minority of cases, by encounters with distinct boundaries in the solar wind itself. By examining dropouts of the first type, we relate differences in the dropouts between the ion and electron data to the source regions. Electron and ion dropouts are observed to be coincident in about half of events, suggesting electron and ion source regions have some offset at least half the time. However, for the particle events observed within ICMEs, the electron and ion dropouts are always coincident, suggesting that the particle acceleration regions for ions and electrons in these events are cospatial.
