 The recent proposal suggests that ripples in the bow shock of the interplanetary magnetic field, IMF, may cause localized high-speed flows in the magnetosheath. These jets are capable of having a dynamic pressure much greater than that of the solar wind, and they were observed by the cluster spacecraft on March 17, 2007. The authors studied the effects of these jets on the magnetopause, the magnetosphere, and the ionosphere, finding that the jets had a scale size of up to 5 Earth radii, RE, and that they caused significant local magnetopause perturbations due to their high dynamic pressure. During this period, irregular pulsations at the geostationary orbit and localized flow enhancements in the ionosphere were also detected. The authors suggest that these intermagnetospheric phenomena were caused by the magnetosheath jets. This article was authored by H. Heidela, N. Partomies, T. V. Leitnin, and others.
