AB: We combine observations from five different spacecraft: Helios 1, Helios 2, IMP-8, Voyager 1 and Voyager 2, from November 1977 to February 1978 (ascending phase solar cycle 21). During this period the large-scale dynamics of the solar wind near the ecliptic plane was characterized by transient forward shocks, ejecta, unstable corotating interaction regions and complex and variable magnetic sectors. We compare the solar wind observations of the five spacecraft to illuminate some aspects of the longitudinal extent and radial evolution of these large-scale events in the solar wind.
