We present observations from Voyager 2 of CIRs and merged CIRs in the outer heliosphere. The rather simple characteristics of the CIR-associated changes in plasma, magnetic field, and particles become more complex as observations are made at greater and greater distances. Picked-up ions from charge exchange undoubtedly play an important role in the structure, but the full details are not yet understood. ©1999 American Institute of Physics.
