000004430 520__ $$aNearly all space weather phenomena can be traced back to the variable magnetism of the Sun. On long time scales, this variability is characterised by the 11-year solar cycle that modulates the number of sunspots on the solar disc and by the 28-days solar rotation that brings the sunspot in and out of Earth's view. The most dramatic space weather phenomena however occur erratically, on shorter timescales from minutes to hours: Solar flares and coronal mass ejections are the most energetic explosions in the solar system and can pose serious risks for modern technology and even human health. This presentation will be a triptych, subsequently addressing (1) the physics of the solar origin of space weather, (2) the potential impact of space weather on contemporary society, and (3) space weather services at ROB and elsewhere in support of risk mitigation strategies
