Oscillating relic magnetic field in the Sun can explain solar long-term evolution and systematic hemispheric asymmetry

Sun is a magnetic star whose magnetic field is generated in the upper third of solar interior by the motion of charged particles called solar plasma. Upward transport of hot plasma and differential rotation form a system of electric currents that produce magnetic fields. This is called the solar dynamo...

Carrington Event 1859 – Reconstructing Historical Space Weather Events

What is Space Weather and how does it affect us?Space weather is the result of particles emitted by the Sun, termed the solar wind, interacting with the Earth's magnetic field. Large eruptions from the Sun, called Coronal Mass Ejections (CMEs), pose a hazard to the ground infrastructure, such as the...

Opportunities and challenges with palaeomagnetic data sources

In our quest to understand the geomagnetic field of past millennia, we rely on two primary sources of data. The first source is archaeomagnetic data, which provides us with valuable information about the geomagnetic field based on ancient artefacts. However, one major challenge we encounter is the uneven...
