Several solar spacecraft have been observing the Sun over the past few years: SoHO, Stereo, Hinode, SDO and most recently IRIS.  We now have detailed images and movies of the Sun, which show that it is very complex and dynamic. This talk will review what we have learnt about our Sun from these space observations, in particular what we know about solar activity and solar flares, together with the impact that the Sun can have on the Earth’s environment (space weather).

Please note that attendance is on a first-come, first-served basis. There is no charge, and doors open 30 minutes before the start of each lecture. No admittance once the lecture has begun.
