UK Met Office opens 'solar storm' centre UK Met Office opens 'solar storm' centre

A new forecast centre dedicated to space weather has officially opened in Exeter. The Met Office has opened a new forecast centre dedicated to so-called "space weather".
The Met Office Space Weather Operations Centre is designed to protect the UK's economy and infrastructure from severe events caused by space weather. The term describes the disruptive influence that storms at the surface of the Sun can have at Earth.

Solar storms are now listed as one of most serious threats on the National Risk Register, along with flu and volcanic eruptions in Iceland. These phenomena are considered to have the potential to cause major economic upheaval, and the government has ordered contingencies be put in place to help protect the UK. "The Prime Minister (David Cameron) and the President of the US (Barack Obama) paved the way for the launch of this operational service in their bilateral discussions in 2011," the minister explained.
Space weather has long been recognised as an issue, but experts say our increasing dependence on technology has made modern society more vulnerable. "Space weather is a serious threat, with the potential to have a very significant effect on society and the economy of our two countries."
Advance notice
Solar storms are now listed as one of most serious threats facing the UK on its National Risk Register, along with flu and volcanic eruptions in Iceland.

Explosive eruptions from the Sun can have a wide range of effects on modern infrastructure.Explosive eruptions from the Sun can have a wide range of effects on modern infrastructure.
A large solar flare can induce huge currents in electricity networks, leading to power outages that can last hours, days and even weeks. The magnetic fields in the biggest outbursts can induce currents in electricity networks that overload equipment and cause power outages.
Scientists recall a particularly powerful event in 1859. Described by the English astronomer Richard Carrington, this outburst buffeted the Earth's magnetic field, producing spectacular auroral lights. The electric fields generated in wires were said to have caused fires in some telegraph stations. Mark Gibbs, the head of space weather at the Met Office, told the BBC: "We're working with critical national infrastructure operators to protect UK PLC. Our forecasts will help those operators take measures to mitigate the risks, so that hopefully we don't see major problems occurring."
Lloyds of London, the insurance market, completed a study in 2012 that examined how the US power grid would cope with a repeat event. The National Grid is already using the service.
It believes its network's architecture makes it inherently robust, but the director of safety sustainability and reliance, Chris Train, said the new Met Office service was invaluable.
"It's fantastic that we now have these forecasts in the UK. Getting a space weather warning allows us to reconfigure the grid to reduce the loading on any vulnerable transformers. It really does help us to get our operational mitigation in place."
Scientists recall a particularly powerful event in 1859. Described by the English astronomer Richard Carrington, this outburst buffeted the Earth, producing spectacular auroral lights right across the globe. It is said that electric fields generated in wires caused fires in some telegraph stations.
Lloyds of London, the insurance market, completed a study in 2012 that examined how the US power grid would cope with another Carrington event.
It concluded that the damage to critical transformers could leave some consumers with no networked electricity supplies for a period between 16 days and anywhere up to two years, resulting in economic losses that run from $0.6 trillion to $2.6 trillion.It concluded that the damage to critical transformers could leave some consumers with no networked electricity supplies for a period between 16 days and anywhere up to two years, resulting in economic losses that run from $0.6 trillion to $2.6 trillion.
"Things like satellite navigation and power grids represent critical nodes in the world economy, and if they are taken out even for a short time, the impacts can be immense," said Lloyds' Nick Beecroft."Things like satellite navigation and power grids represent critical nodes in the world economy, and if they are taken out even for a short time, the impacts can be immense," said Lloyds' Nick Beecroft.

Dedicated eyes
A key concern for the future is the continuation of the important tools that gather the data for the forecasts. Some are ageing.
One major provider is the Soho spacecraft that sits about 1.5 million km from Earth and stares constantly at the Sun.
"Ten to 15 years is tops for a spacecraft and Soho will be 20 next year," observed Mike Hapgood, a space weather expert with the Rutherford Appleton Laboratory.
"We have ideas for future instruments with the European Space Agency, and we're also developing new radio astronomy techniques that we believe can help."
The Airbus Group has a concept for what would be a dedicated space weather mission called Carrington.
This would trail the Earth in its orbit around the Sun, employing a range of instruments to pick up solar activity before it causes problems on Earth.
