There has been an increase in activity on the Sun over recent days with a number of Coronal Mass Ejections (CMEs) taking place. A high energy X Ray flare was released from the Sun early this morning, and this has sent a very fast CME towards the Earth at speeds up to 2000 km per second. At present this is expected to reach the Earth from Thursday morning.
Working with our partners at the British Geological Survey (BGS), through the Hazard Centre at the Met Office, we have provided advice on the nature of this event so that government and industry can take steps to mitigate the potential impacts a geomagnetic storm may bring, for example to the airline and power supply industries.

The impact of this will mainly be in terms of a geomagnetic storm on Earth and we understand some airlines may re-direct flights from polar routes and that the power supply industry may take routine mitigation steps.
At the governmental level UK Prime Minister David Cameron and US President Barack Obama have welcomed the growing partnership between the Met Office and the U.S. National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service towards the delivery of space weather advice and alerts. A memorandum was signed between the Met Office and NOAA in February 2011.
The Met Office, as part of its Natural Hazards Partnership, is working with the BGS on developing a space weather capability. We have recently become a member of the International Space Innovation Centre (ISIC) where a major focus of our activities will be around the influence of solar events on the earth and its surroundings.
