Galactic cosmic rays are entering the heliosphere from the interstellar

medium, while anomalous cosmic rays are believed to be pickup ions

accelerated at the heliospheric termination shock. Both particle

species are modulated by the solar wind and the heliospheric magnetic field.

Since 1997 solar activity increased and as a

consequence the flux of galactic and anomalous cosmic ray decreased.

In this paper we will discuss the variation of low energy anomalous

cosmic rays as measured by the Ulysses Energetic Particle Composition

Experiment (EPAC) on board Ulysses. Specifically we are addressing the

question: Are there differences in the modulation of galactic cosmic rays

and what are possible implication for the modulation of cosmic rays in the

heliosphere?
