16 Forecasting Space Weather Solar dynamo (generation of the Sun’s magnetic field) 3D topology and evolution of sunspot fields. Schrijver & Title Muñoz-Jaramillo

17 Forecasting Space Weather Solar dynamo (generation of the Sun’s magnetic field) 3D topology and evolution of sunspot fields. What makes the magnetic fields of sunspots erupt?

18 Forecasting Space Weather How much energy is released in the eruption? How will it propagate outwards into the interplanetary medium? Determining the direction of B at the magnetopause. SunEarth C. de Forest (SwRI)
