B. Helicity & CMEs
Relevance: Quest I, Campaign 2 – The effects of solar variability on the solar atmosphere and heliosphere
 
The story behind the headline:
•Twisted magnetic flux tubes emerge to form solar filaments
•Twist related to CMEs
•Twisted coronal structures (sigmoids) observed correlated with
   eruptions
•Earth-directed (halo) CMEs relate to disturbances at Earth
•Filament cavities è flux rope at 1 AU
•Filament cavities might arise from streamers è STEREO
Solar eruptions come from twisted magnetic fields
