Session ID#: 12525

Session Description:
Space weather events are driven by eruptive activity originating on the Sun. The plasma dynamics and radiation signatures depend on the magnetic field configuration in the lower solar atmosphere, whereas the magnetic environment in the intervening heliospheric volume determines its geo-effectiveness. This session focuses on the complex magnetic environment from the Sun to 1 AU, knowledge of which is crucial to understanding and forecasting solar eruptions and their impact on Earth. We invite contributions that preferably combine (theoretical and observational) knowledge taken from two or more of the following themes: the energy budget and stability of solar active region field; the predicability of CME productiveness of solar flares; the special magnetic topology responsible for SEP and gamma-ray production; the remote-sensing and in-situ magnetic signatures of flux ropes; or the mapping of magnetic field from the interplanetary space to the Sun.
