One of the most powerful solar events observed over the current cycle occurred at 1024 July 14, 2000 accompanied by an X-5.7 x-ray burst and a full halo coronal mass ejection that initially was traveling at a velocity of > 1700 km/s. At earth the solar energetic particle event was the largest so far in cycle 23. Some 177 days later (2001.02) at V-2 (63 AU, 24ºS) there began a step decrease in the cosmic ray intensity (15% for 265 MeV/n GCR He) and a complex enhancement with multiple structure in the magnitude of the interplanetary magnetic field. For lowenergy 2.3 MeV protons there was a 10-fold increase in intensity that tracks the increase in the solar wind velocity which reached a peak value of ~450 km/s. This event is discussed in the context of the increases in intensity of MeV ions and the modulation events for galactic and anomalous cosmic rays that have been observed in the distant heliosphere for solar cycle 23 through 2001.4.
