IRDR0007: Space Weather and Technological Failures (20/21)
Module Tutor Professor Peter Sammonds Contact details: p.sammonds@ucl.ac.uk
Course Synopsis Space weather was added to the UK National Risk Register in
2012 and is currently graded as the fourth highest civil emergency risk to
the UK. The USA has a similar assessment of the impact of severe space
weather and as we increasingly rely on technology for essential services
the risk will continue to grow. Yet, very few people have any idea what
space weather is, how it may impact the Earth or how to respond to it. In
this course we will cover the underlying physics of the outer space
environment, understand how the varying behaviour of the Sun impacts outer
space, the Earth, people and technology. We will gain knowledge of the
forecasting of space weather, how response to severe space weather is
changing and what our vulnerabilities to space weather are. The course will
also compare space weather to other forms of risk from outer space, such as
space debris and meteorite impacts. The module will consider the following
topics: The history of space weather Solar activity cycle Sunspots Solar
flares and solar eruptive events The Earth’s magnetic field Geomagnetic
storms and aurora The radiation environment in deep space (cosmic rays,
solar energetic particles) and in the inner magnetosphere (radiation belts)
Ionospheric and ground-induced currents The impacts of space weather
Vulnerabilities to space weather: satellites, electrical power grids, radio
and radiation Space weather forecasting and international response to space
weather Space debris and collision probability Extraterrestrial impactors
These topics will be covered in a series of lectures, with a field trip to
the Met Office Space Weather Operations Centre to see how the UK forecasts
space weather.
