  We present a recent analysis with 1996 SOHO CELIAS CTOF data, which reveals
correlations of He+ pickup ion fluxes and spectra with the magnetic field
strength and solar wind density. The motivation is to better understand the
ubiquitous large variations in both pickup ion fluxes and their velocity
distributions found in interstellar pickup ion datasets. We concentrate on time
periods of that can be associated with compression regions in the solar wind.
Along with enhancements of the overall pickup ion fluxes, adiabatic heating and
acceleration of the pickup ions are also observed in these regions. Transport
processes that lead to the observed compressions and related heating or
acceleration are discussed. A shift in velocity space associated with traveling
interplanetary compression regions is observed, and a simple model presented to
explain this phenomenon based on the conserved magnetic adiabatic moment.
