Abstract We analyse the possibility that the shock termination of the solar wind should occur at a heliocentric distance of 50 a.u. It is concluded that this is possible if the density of the interstellar medium near the Sun is of the order of 0.5 cm−3, or the pressure of low energy cosmic rays (less than about 300 MeV/nucleon) is of the order of 6×10−12 dyn cm−2, or the interstellar magnetic field strength is of the order of 8 microgauss, or some suitable combination of these. Such conditions would not normally be expected to prevail in the interstellar medium in the neighbourhood of the Sun. However, the possibility that a supernova explosion occurred nearby some 105–106 years ago must be taken seriously and in such circumstances the required conditions may be relatively easily achieved.
