A powerful solar storm that could cause havoc with satellites and radios across the country is set to strike, forecasters have warned.
The geomagnetic space storm, categorised as 'strong' by the Met Office, could impact the UK as well as further afield until 3am on Thursday.
It could also bring with it a spectacular show with the Northern Lights seen as far south as mid Wales and the Midlands.
A warning for the planet is in place until 3am for the so-called 'G3 level storm.'
Forecasters at the Met Office said of its possible impact in the UK: "Intermittent GNSS(GPS) satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent.
"Aurora may be seen in Scotland and Northern Ireland and as low as Mid-Wales and the Midlands."
The storm is described as a “cannibal” because it ate one of its own kind, the Daily Star reported. The fast-moving coronal mass ejection caught up with a series of smaller ones and absorbed them.
Elsewhere, experts say the storm could trigger false alarms on some protection devices as well as orientation problems with satellites.
The geomagnetic storm was spotted by NASA's Solar and Heliospheric Observatory (SOHO), a spacecraft that orbits between the Earth and the Sun and monitors solar activity.
The body said on social media: "And yet another spectacular halo CME [coronal mass ejection] directed towards Earth.
"This one was produced by AR 12981 near the central meridian and erupted just a few hours after a another large CME from AR 12887.
"Let's hope that this one will produce more impressive aurorae than the Halloween storm."
It comes after many in the UK spotted the Northern Lights after a massive solar flare triggered the breath-taking spectacle.
The flare was said to be the strongest storm in the current weather cycle as the Met Office said they received reports from many saying they saw the phenomenon in the UK.
A huge burst of radiation from the sun on October 28 had been predicted to reach Earth after a 92 million mile journey.
The cloud of electromagnetic particles causes a colourful display in the atmosphere which can be visible from parts of the Northern Hemisphere.
The flare is the result of a coronal mass ejection (CME) - a huge expulsion of plasma from the Sun's corona - or outer layer.
Solar flares can affect the planet's magnetic field, which in turn can disrupt power grids and communications networks.
NASA's Solar Dynamics Observatory, which tracks the Sun's activity, captured an image of the flare last Thursday.
#It had already caused radio blackouts in parts of South America, according to the U.S. Space Weather Prediction Center (SWPC).
Nasa said: "Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground.
"However - when intense enough - they can disturb the atmosphere in the layer where GPS and communications signals travel."
Geomagnetic storms are large disturbances in the Earth's magnetic field caused by changes in the solar wind and interplanetary magnetic field (IMF) structure.
These changes in the solar wind arise from disturbances on the sun, such as in powerful coronal mass ejections (CMEs).
Their effect can be felt for a number of days.
A further storm watch is in place until Friday morning.
