We often take for granted that the technology we have become so accustomed to rely on daily can be affected not only by weather on Earth but also by more extreme weather in space.
An extreme space weather event, or solar superstorm, is one of a number of potentially high impact, but low probability natural hazards. In response to a growing awareness by governments, extreme space weather now features as an element of national risk assessment in numerous countries.
Solar superstorms can have detrimental effects on the power grid, satellites, avionics, and aircraft over polar regions, High Frequency (HF) radio communication, mobile telephones and GPS systems, to name a few. Space weather has consequently been identified as a risk to the world economy and to society. In the UK solar storms are listed as the fourth most serious threat on the National Risk Register and are recognised as having a potential significant impact on the UK's critical national infrastructure.
