Abstract The way in which information propagates in the solar terrestrial system is of central importance to understanding solar terrestrial coupling. A comparatively understudied region is the magnetosheath and we exploit a fortuitous positioning of spacecraft to examine the transmission of information through the shock and magnetosheath. Cross-correlation of spacecraft signals shows that much of the low frequency magnetic field variation in the sheath appears to propagate through from the interplanetary medium with increased lag as one approaches the magnetopause. There are two types of event distinguished where a magnetosheath signal appears to have no counterpart in the solar wind. In one case, the sheath signal is periodic. The second cases are flux transfer events encountered near the magnetopause.
