CO-ROTATING PARTICLE ENHANCEMENTS OUT OF THE ECLIPTIC-PLANE

The characteristics of the recurrent electron (38-53 keV) and ion (>si milar to 0.5 MeV) enhancements observed by Ulysses from mid-1992 to Ap ril 1994 are presented. The magnitude of the ion flux increases reache d a maximum at a latitude of similar to 20 degrees S and decreased aft erwards by similar to 23%/degree until early 1994. The magnitude of th e electron increases showed a similar trend until May, 1993, after whi ch time it became approximately constant, until it started to increase again in early 1994. The electron enhancements have lagged the proton s by up to 5 days once Ulysses left the heliospheric current sheet (mi d-1993). The electron spectral index tended to harden (a) during the d ecay of the event and (b) as the latitude increased, up to 50 degrees S. The events have recurred on a 26.0 day period, but with significant phase shifts over the 25 rotations studied. The H/He ratio decreases across the maximum intensity. The mean minimum value for H/He was 3.5 +/-0.3, lower than that measured in previous studies in the ecliptic p lane.
