5 November 2015Working with scientists in 14 countries across Europe, ESA is developing a warning network that will help protect us from the effects of our Sun’s activity.ESA’s Space Situational Awareness efforts now generate almost 60 ‘products’ – including high-quality measurements, forecasts, alerts and expert analysis – from teams participating in the Agency’s space weather network, heading for over 140 next year.Many use realtime data on our Sun and the resulting disturbances detected in the environment around Earth, our atmosphere and down to the surface.

The raw information is gathered from a large and increasing number of ground and space sensors, and delivered through a network of Expert Service Centres, established by ESA to combine and build on existing facilities in Member States.

“The Centres federate the wealth of space weather expertise and capabilities that exist at the national level,” says ESA’s Alexi Glover, responsible for network development.

“This provides a large added value not only to our Member States and their industries but to Europe as a whole.”

Watching out for space weather

Numerous sectors are potentially affected by space weather in Europe’s economy, ranging from telecoms, broadcasting, drilling, exploration, navigation and power distribution, the latter especially at northern latitudes.

The Sun causes ‘storms’ within Earth’s magnetosphere when giant eruptions from the Sun’s outer atmosphere – coronal mass ejections (CMEs) – wash across our planet. The most recent very large event occurred in 2012, though it missed Earth. Lesser CMEs happen regularly and do reach the planet, affecting daily economic activities.

ESA launched its space awareness effort in 2009 in part to develop a Europe-wide capability to monitor, study and warn about such space weather effects.

Building a robust European network

“The current expansion of the network, interconnected via ESA’s Space Weather Coordination Centre in Brussels, Belgium, brings …
