Automatically detected bridge and PAF-like arcs (in pale red and blue) in all northern-hemisphere HST-STIS observations we considered, mapped via flux-equivalence mapping to the magnetospheric equator (radius and local time). The radii are given in R_J. A set of average bridge and PAF contours is given in dark red and blue; their starting locations on the Joy et al. (2002) expanded magnetopause (solar wind ram pressure = 0.039 nPa; stand-off distance 92 R_J) are given in black.
