Our dynamic Sun
Tue 21 March 2017, 18:00 – 19:00 GMT
The Sun, our star, has just passed the peak of its activity cycle. Several solar space observatories have been watching the Sun over the past 20 years. Dr Helen Mason reviews what we have learnt from these about our dynamic Sun, what we know (and don't yet know!) about sunspots, solar active regions and flares, and how the Sun affects the Earth's environment.
