On page 1447 of this issue, Lallement et al. report exciting new observations of the local interstellar medium, just beyond the boundary of the heliosphere (the region influenced by our [...]

Three-dimensional simulations of the heliospheric modulation of galactic cosmic ray protons show that corotating variations in the intensity can persist to quite high heliographic latitudes. Variations are seen at latitudes considerably higher than the maximum latitude extension of the heliographic current sheet, in regions where the solar wind velocity and magnetic field show no significant variation. Similar conclusions may apply also to lower energy particles, which may be accelerated at lower latitudes. Cosmic ray variations caused by corotating interaction regions present at low heliographic latitudes can propagate to significantly higher latitudes., Observations of periodic variations of the cosmic ray intensity, associated with corotating regions in the solar wind, are a useful diagnostic of the modes of transport of cosmic rays.
