The wealth of observational data from multiple spacecraft currently in operation at different locations around the inner heliosphere can set constraints to the morphology and topology of various solar and heliospheric structures, such as coronal holes, active regions, prominence eruptions, streamers, Extreme Ultra Violet waves, co-rotating interaction regions and coronal mass ejections (CMEs) to name a few. Furthermore, such observations can provide valuable information regarding the propagation behavior of transient structures. This behavior is governed to a high degree by the ambient magnetic field and plasma flow in which these structures are embedded, which has important effects on the geo and planetary-effectiveness of, for example, CMEs. As such, the preconditioning of interplanetary space has immediate consequences for predicting the arrival times and impact speeds of CMEs and is, therefore, an important parameter for (Planetary) Space Weather forecasting.
This session focuses on studies covering observations at multiple vantage points, remote and in-situ, as well as theories and simulations from which the structuring of interplanetary space may be identified and how this may affect disturbances evolving in the inner heliosphere.
