INTERNATIONAL LIVING WITH A STAR

摘要

The response of our space environment to the constantly changing Sun is known as "Space Weather". Sudden ejections of plasma and magnetic field structures from the Sun's atmosphere called coronal mass ejections (CMEs) together with sudden bursts of radiation termed solar flares all cause space weather effects at the Earth. The International Living With a Star (ILWS) programme is a space weather focused and applications driven research programme. Its goal is to develop the scientific understanding necessary to effectively address those aspects of the connected Sun-Earth system that directly affect life and society. Recent large solar storms caused damages to power systems and satellites and disturbed important navigation and communication systems. Furthermore, accurate monitoring of the energy output from the Sun is important for understanding how the Sun contributes to the observed warming of our planet. The Sun is a variable star we better learn how to live with.
