This covers the solar minimum in the A>0-solar magnetic epoch, the solar magnetic reversal to an A<0-magnetic epoch at solar maximum and the declining phase of solar cycle 23. In order to calculate the galactic cosmic ray intensity distribution in the inner heliosphere we used the 125-250 MeV/nuc helium channel from KET and a combination of carbon channels from the CRIS instrument on ACE. Our analysis results in a radial and latitudinal intensity gradient of Gr=4.5±0.6%/AU and Gθ=0.03±0.04%/degree, respectively. Note, that the positive latitudinal gradient is observed in the current A<0-solar magnetic epoch, when a negative gradient was expected. Wait for Ulysses fast latitude scan in 07/08
