Sola r magnetism � generated b y enigmatic dynamo p ro cesses in the sola r interio r � o rganised into highly complex patterns of sola r activit y � dominates the structure of the outer sola r atmosphere � regulates the sola r wind � a�ects the extended heliosphere

Europ ean Solar Magnetometry Net w ork WHA T? � Science Ob jectiv es { cha rt the top ology of sola r magnetic structures at all scales of emergence at the sola r surface { identify the basic p ro cesses underlying the dynamical b e- haviour of sola r magnetic structures { measure sola r activit y patterns to constrain the sola r dynamo mechanism � Implemen tation Ob jectiv es { imp rove sola r magnetometry to unp recedented angula r res- olution and sensitivit y { obtain comp rehensive high-resolution sola r magnetometry data in concert with space data { achieve observationally constrained numerical mo delling 25 20 15 10 5 0
