摘要
We are presenting a study of interplanetary shock shapes as observed by multiple spacecraft in the solar wind. The analysis of the 1 May 1998 shock observed by six spacecraft is presented in detail as an example to demonstrate possible complex shock shapes with small- and large-scale curvatures of the shock surface. To systematically estimate the shock front deviation from planarity on different scales, we are presenting an analysis of 62 shocks observed by Wind and at least one other spacecraft. Our results show the presence of local (on scales up to similar to 30 R(E)) shock curvatures with radii of less than similar to 50 to similar to 200 R(E) for the majority of analyzed shocks. On larger scales, the shock curvature decreases and reaches the limit of the strongest possible curvature with radius of similar to 400 R(E) on scales greater than similar to 100 R(E) for all analyzed shocks.
