Space weather forecast: Solar storm to hit Earth TOMORROW - Express.co.uk

A hole has opened up in the atmosphere of the Sun, allowing for a stream of solar winds to be released. weather forecasters are predicting the solar winds to hit Earth tomorrow and for the following day, which could leave to auroras in the upper echelons of the northern hemisphere.

The particles are currently making their way across the 150 million kilometre journey from the Sun to Earth, where they are expected to arrive on May 19.

Cosmic forecasting site Space Weather said: "A minor stream of solar wind is expected to buffet Earth's magnetic field on May 19th and 20th.

"The gaseous material is flowing from a small hole in the sun's atmosphere. Geomagnetic unrest could spark polar auroras."

Auroras, which include northern lights – aurora borealis – and southern lights – aurora australis, are caused when solar particles hit the atmosphere.

As the magnetosphere gets bombarded by solar winds, stunning blue lights can appear as that layer of the atmosphere deflects the particles.

However, researchers also note the consequences of a solar storm and space weather can extend beyond northern or southern lights.

For the most part, the Earth’s magnetic field protects humans from the barrage of radiation which comes from sunspots, but solar storms can affect satellite-based technology.

Solar winds can heat the Earth’s outer atmosphere, causing it to expand.

This can affect satellites in orbit, potentially leading to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.

Research from the University of Warwick and the British Antarctic Survey analysed the last 14 solar cycles, dating back 150 years.

The analysis showed that ‘severe’ magnetic storms occurred in 42 out of the last 150 years, and ‘great’ super-storms occurred in 6 years out of 150.

The researchers said if it had hit Earth, it could have downed technology on our planet.

Lead author Professor Sandra Chapman, from the University of Warwick’s Centre for Fusion, Space and Astrophysics, said: “These super-storms are rare events but estimating their chance of occurrence is an important part of planning the level of mitigation needed to protect critical national infrastructure.

“This research proposes a new method to approach historical data, to provide a better picture of the chance of occurrence of super-storms and what super-storm activity we are likely to see in the future.”
