AB - Ulysses, the first spacecraft ever to fly over the poles of the Sun, plays a central role in the Heliospheric Network, the international fleet of spacecraft to explore the Sun and Heliosphere. In November 2006, Ulysses began its passage over the Sun's south pole for the third time. Although like during the first polar passes in 1994/1995 the Sun is again close to its activity minimum, an unexpected rise of solar activity occurred in December 2006. Active Region 10930 produced a series of major solar flares with the strongest one (X9.0) recorded on December 5 after it rotated into view on the solar east limb. We present energetic particle observations by Ulysses located at >70 deg south heliolatitude during this period and discuss their implications for particle propagation to solar polar regions. The observed events are also compared with previous Ulysses high latitude measurements obtained close to solar maximum. Furthermore, comparisons with data acquired from ACE - another spacecraft of the Heliospheric Network - near the ecliptic plane are discussed.
