AB: We document the presence and properties of solitary structures in the electric field at an interplanetary shock and Saturn's magnetosphere. The data are from the Cassini Radio and Plasma Wave Science (RPWS) instrument as Cassini cruised beyond 8 AU and approached Saturn. The interplanetary shock was associated with the record-making November 2003 solar flares. The shock transition was followed by a region that has signatures of a magnetic cloud. Solitary waves started to appear at the foreshock, most intensely around the shock transition, and no solitary waves were observed within the magnetic cloud. At Saturn, solitary waves appeared primarily at the bow shock, and near the closest approaches of Saturn and its moon Titan where there are abrupt changes in the magnetic field. The background magnetic field strength at which solitary waves were obserevd ranges from 0.1 nT to ~8000 nT, extending the plasma regime where solitary waves have been observed previously at Earth.
