Abstract:
How did the evolving structure of the heliospheric magnetic field in January 2014 affect the propagation of field and particles from the Sun to Earth? Energy build-up on local and regional size scales led to an X-class flare and coronal mass ejection, but the post-launch trajectory taken by the disturbance was unexpected. Frequently updated full synchronic maps of the solar magnetic field are used to calculate changes in the global coronal and heliospheric field.
