We present five events of SLAMS (short large-amplitude magnetic structures) detected upstream of the quasi-parallel bow shock of Saturn. The events were discovered and further analyzed using the measurements of the Cassini Plasma Spectrometer and the Magnetometer instruments of the Cassini spacecraft. Directional, speed and temperature analysis of the charged particles in the vicinity of the SLAM structures is presented. We also analyze the effect of upstream parameters (especially the IMF and cone angle) on the ULF wave frequency and subsequent SLAMS formation. We use a simple empirical model to estimate location of the bow shock related to the SLAMS observations. We also discuss the spatial characteristics of SLAMS observed near Saturn by extrapolating the measurements and morphology derived by the four Cluster probes at Earth.
