Solar storm will hit Earth: Images of Aurora lights

Spectacular images of a spectacular light show triggered by a solar storm hitting Earth roll with aurora lights seen over Australia.

Skywatchers saw the Northern Lights as a stunning nighttime image of geomagnetic storms hitting Earth this week and aurora lights are expected from Australia.

Eyes were drawn to the shining sky above the north of England, Scotland and parts of Northern Ireland.

For other areas, however, the cloud is likely to block the green hue of the auroras caused by the great solar storm.

Solar storms are caused by a type of solar flare called a coronal mass ejection – a massive ejection of plasma from the Sun’s outer layer called the corona.

According to the U.S. Space Weather Prediction Center, the solar event could cause “orientation irregularities” as well as fluctuations in the power grid for spacecraft.

This happens when a massive explosion of material from the sun causes a phenomenon known as a geomagnetic storm that interferes with Earth’s magnetic field.

Australians have been told to watch out for the aurora lights expected from Tuesday night.

The rare event prompted the Brits to go out last night and try and capture the perfect shot.

A primary school teacher in Kirkwall, Scotland, shared four photos of the night sky.

Ms. H Pinner tweeted that she had “a definite flash of aurora” as she searched for the Northern Lights over her home.

“We’ve been watching the aurora for several hours and all we can see is a green glow on the other side of the clouds. Our observation continues!” said Julie Calderwood Fitzsimmons of Orkney, on Scotland’s north coast.

Meanwhile, Birmingham resident Daniel Tonks shared dazzling photos of the Northern Lights from Iceland.

Other spectacular displays can be seen in Canada and Norway.

Dr Beth Keith said she “takes the kids to the heights to look at a very cloudy sky” before returning to Sheffield, where the only Northern Lights “we’ve seen tonight” are dimmed by the dark, cloud-filled sky. .

The UK Met Office said the aurora “is most likely to occur over most of Scotland and perhaps extends into northern England and Northern Ireland tonight”.

A spokesperson said, “For many in these areas it will be very cloudy, but some spots have luck.” said.

“Aurora is possible up to 11th and 12th across most of Scotland, but cloud amounts are increasing which means sightings are unlikely for most,” the agency said.

Tom Kerss, astronomer and author Northern Lights: The Definitive Guide to Aurorasurged people to look anyway, despite the heavy cloud forecast.

“Unfortunately, I think cloud cover will be a bit of an issue for Scotland, but that doesn’t mean you shouldn’t go if you have any clear patches,” he said.

The forecaster says the solar storm “probably has advanced pockets of energy within it, so it can often spike in performance.”

“And that means it’s quite possible that auroras are indeed reaching north of England and perhaps as far south as Belfast or Omagh – not far south,” Kerss said.

“But they can become visible over the sea from anyone looking north of England.”

He added that the chances of disruption in the UK are low due to space weather forecasting and electrical engineering.

“We wouldn’t expect power loss or any transformers to blow up or a storm of this magnitude.

“But it’s possible that super solar storms like the one that occurred about 150 years ago are causing widespread disruption – we’re lucky it hasn’t happened yet.”

Satellite navigation alert

In an update on Monday, the Space Weather Prediction Center said its observation of moderate geomagnetic storms continues Oct.

“The aurora can usually be observed somewhere on Earth just after sunset or just before sunrise,” the experts added.

“The aurora is not visible during daylight hours, (it) need not be directly overhead, but can be observed from up to 1000 km away when the aurora is bright and conditions are favorable.

Aurora is an indicator of current geomagnetic storm conditions and provides situational awareness for a range of technologies.

“(This) directly affects high-frequency radio communications and GPS/GNSS satellite navigation.

“It is closely related to earth-inducing currents that affect the electric power transition.

“For many people, the aurora is a beautiful nocturnal phenomenon worth traveling to the Arctic regions just to observe.

“It’s the only way for most people to truly experience space weather.”
