The authors present an analysis using statistical methods of a large number of observations of weak double layers and solitary waves in auroral regions, made from Viking spacecraft. Such structures, supporting non-neutral plasma regions, exhibit voltage drops along field lines, and are a possible explanation for ion acceleration mechanisms in the auroral region. The authors show that these events are found in conjunction with beams of upward flowing ions. They are primarily seen in the altitude range 7 to 11,000 km. They are seen in groups which may have perpendicular extents of a few km.
