The Ulysses south polar pass: Energetic ion observations

We present here a preliminary analysis of observations of energetic ions during the first polar pass of the Ulysses spacecraft, concentrating mainly on the region where the spacecraft was continually immersed in high speed flow from the polar coronal hole. During the ascent to high latitudes, a single recurrent peak was observed once per solar rotation. From 70°S during ascent to 43°S during descent no major peaks were observed. Thereafter, two peaks per solar rotation were observed.
