Help explore recent progresses in our understanding of the heliospheric properties of coronal mass ejection (CMEs) during a session at the Fall AGU Meeting in San Francisco, 15-19 December, 2008.

The deadline for on-line submission of abstracts is during September 3 at 23:59 ET.

With the launches of SMEI and STEREO, the development of IPS and the multiplication of planetary orbiters, we now have access to a number of remote-sensing observations of coronal mass ejections from vantage points outside of the near-Sun and near-Earth environments. These capabilities are enabling a better understanding of CME properties beyond the traditional coronagraph fields of view (< 0.15 AU), in particular regarding the CME kinematics and the evolution of the density and the magnetic field of the ejecta before they reach Earth.

This session solicits papers on CME properties beyond 0.1 AU. We are particularly interested in model-model, model-observation and observation-observation (multi-spacecraft) comparisons, which can help answer questions about CME acceleration, rotation and deflection in the heliosphere, the 3-D nature of CMEs, and the angular extent of the shock waves and ejecta. We also solicit papers examining planned CME observations from past and future spacecraft (Helios, Solar Probe, Solar Orbiter) and from planetary missions such as Messenger, Venus Express and Mars Express.
