%T Solar wind and interplanetary shock parameters near Saturn's orbit(~10 AU)
%V 165
%X In this work, in-situ 1-h averaged plasma and magneticfield spacecraft data are used to characterize solar wind conditions near Saturn's orbit. Further, high resolutionsolar wind interplanetary data are used to identify and to calculate interplanetary shock parameters. When only plasma or magneticfield data are available, identifieddiscontinuities were classified as possible shocks. Solar wind parameters at 10 AU decrease as expected from the inner heliosphere averages. For instance, solar winddynamic pressure is ~2% and ~40% of its value at 1 and 5 AU, respectively. Wave magnetosonic speed is similar to 5 AU, but it is only about 60% of the 1 AU value.From analysis of high resolution plasma and magneticfield data, only a small number of shocks (13) were identified, because of scarce data availability. On the otherhand, a larger number of possible shocks (60) were identified. Most of the confirmed shocks (~75%) were fast forward shocks, while ~25% were reverse shocks. Machnumbers ranged from 1.2 to 3.5 (average 2.2). Shock normal angle was on average 68with oblique to perpendicular propagation to the magneticfield. From solarwind and interplanetary shock parameters analyzed in this work, and comparison with results from other works at different radial distances, it is concluded thatconditions for shock occurrence and shock strength seem to increase from 1 to 5 AU and then level off or decrease near ~10 AU, with shock strength at 10 AUcomparable to shock strength at 1 AU. These results are of interest for interplanetary dynamics and for solar wind-planetary magnetosphere coupling.
