Origins of anisotropic 40-300 keV electron events observed at low and highlatitudes

Using a survey of anisotropic electron events in the energy range of simila r to 40-300 keV observed by HI-SCALE on Ulysses, we have selected several t ime intervals during 1999 when Ulysses traveled from about 20 degrees S at 5.2 AU (January 1999) to 42 degrees S at 4.2 AU (January 2000). We compare these events with observations at similar to1 AU using the nearly identical instrument, EPAM on ACE. In order to study the solar origins of these elec trons using the imaging Nancay Radioheliograph, we further restricted the l ist of events to those in which interplanetary magnetic field lines with or igins on the visible solar disk, intersected Ulysses. We find that not all the anisotropic electron events are observed by both spacecraft and there e xists a strong dependence on the spacecraft's magnetic connection back to t he Sun. We have identified the solar origin for five electron events using radio observations, and correlate these with interplanetary type-III radio emissions using the WIND/WAVES experiment.
