Energetic ions observed at low to high latitudes in the southern heliosphere during declining and rising solar activity

We present and compare observations of energetic protons during the two fir st transits of the Ulysses spacecraft from low to high latitudes in the sou thern heliosphere. Protons in the energy range 1.8-3.8 MeV from the COSPIN experiment are studied for global trends and in relation to some ambient st ructures in the solar wind (corotating interaction region, forward/reverse shock). The global trends show the large dependence on the heliospheric con dition and solar activity, including indications of a larger ambient partic le population during the rising phase of solar activity and more efficient solar wind particle accelerators during the declining phase. More enhanceme nts in the proton flux intensity are time associated with forward shocks th an reverse contrary to first pass. Recurrent structures are found even duri ng the second transit. Some latitude dependent periodicities are observed t hat could relate to the differential solar rotation.
