Space Environment Impacts Expert Group – SEIEG

The Space Environment Impacts Expert Group (SEIEG) is an independent committee of experts drawn from Academia, Research Institutes, Companies, and Agencies.

The primary purpose of SEIEG is to assess the science related to space weather, review the impact to people and modern infrastructure, and to provide support and advice to the UK Met Office and Government Departments.

The SEIEG is independent of Government and does not receive funding for the work it undertakes.

Space Weather

Space weather refers to changes in the near-space environment that disrupt modern technology and endanger human health.  Space weather is driven primarily by solar variations and causes disruption to power supplies, satellites, communications, aviation, navigation, pipelines and much more.

Government Strategy

The UK government’s strategy to increase our preparedness and resilience to a severe space weather event.

Meetings

The SEIEG meets twice a year and is hosted by the Department for Energy and Net Zero (DESNZ).  Senior civil servants from other Departments, such as the Department for Transport, also usually attend.

Membership

The SEIEG is composed of a core team, and a wider membership.  The core team includes:

The core team draws on the expertise of the wider membership.

Key Research Findings

Members of SEIEG have published influential reports and research papers which have been independently assessed by international peer review.  These include the Royal Academy of Engineering Report on extreme space weather (Cannon et al., 2013), assessments of the economic impact of a severe space weather event (Eastwood et al., 2018, Oughton et al., 2019) and the development of realistic worst-case scenarios (Hapgood et al., 2021).

These research findings have been used to support the UK National Risk Register (2020, 2023), the National Space Strategy (2021) and the BEIS severe space weather preparedness strategy (2021).
