Is 2024 the year of aurora?

Peer reviewed papers

Amazing aurora!

The dazzling and colourful aurora borealis, or northern lights, observed by many across the UK on 10th-11th May was one of the most extreme and long-lasting geomagnetic storms recorded in the last 155 years. More information on the event.

Blog: Will 2024 be the Year of the Aurora?

The Sun's approximate eleven-year activity cycle is predicted to peak this year, prompting BGS scientists to anticipate that 2024 will be the 'Year of the Aurora'.

Old records and new data for space weather studies

Four recent papers on various aspects space weather have been published: (1) on GICs in the UK power grid Huebert et al. (2024); (2) GICs in the UK railway network Patterson et al. (2024); (3) high frequency magnetic field line vibrations Hodnett et al. (2024); and (4) digital data from the Carrington 1859 storm Beggan et al. (2024).

About BGS Geomagnetism

The Geomagnetism team measures, records, models and interprets variations in the Earth’s natural magnetic fields.

Our data and expertise help to develop scientific understanding of change in the Earth and the environment, from deep within the core out into space.

We also provide geomagnetic products and services to industry and to academic colleagues and we use our knowledge for information and education.
