THE PROPAGATION OF SUB-MEV SOLAR ELECTRONS TO HELIOLATITUDES ABOVE 50-DEGREES-S

On 27 February 1994 when the Ulysses spacecraft was at an heliolatitud e of 54 degrees S low energy electrons (similar to 50-400 keV) and hig h energy protons (14-31 MeV) were measured following a solar flare bey ond the west limb. These measurements show that under favorable condit ions energetic particles can be transported very rapidly across 60 deg rees in heliocentric latitudes to radial distances beyond 35 AU. The i nterplanetary transport occurs inside a structure that was identified as a CME in interplanetary space by Gosling et al. [1994] and that was produced on 20 February. The flare associated with the interplanetary electron event was well documented by the Nancay radio heliograph and was located at 09 degrees N 95 degrees W in the same active region th at can be associated with the earlier origin of the Gosling et al. eve nt. This particle event presents many similarities with the June '93 i nterplanetary particle event observed at 32 degrees S [Armstrong et al ., 1994].
