AB: The CELIAS experiment onboard SOHO and the two Plasma and Suprathermal Ion Composition (PLASTIC) experiments onboard STEREO-A/B provide measurements of velocity, mass and ionic charge of solar wind ions and of suprathermal particles up to energies of 80 keV/e (PLASTIC) and 600 keV/e (CELIAS), respectively. Thus both the SOHO and STEREO instrumentation covers the energy range of the pickup He particle population of interstellar origin that is accelerated to suprathermal energies at interplanetary shocks and corotating interaction regions (CIRs). ACE and SOHO observations showed a large variability of both the pickup He source and the flux of suprathermal particles that so far could not be satisfactorily explained. In this overview we will summarize recent pickup He observations with ACE and SOHO at 1 AU, present first results of pickup He in CIRs obtained with STEREO, and discuss open questions that can be tackled in the near future with the new constellation of several spacecraft in the inner heliosphere.
