Power Grids, Satellite Communications’ Disruption As NOAA Reveals 60% Chance Radiation Storm Hitting The Earth This Week

Power Grids

 

OpenLife Nigeria has gathered that as the earth has yet to fully grapple with last week’s ‘severe’ solar storms, scientists are warning about a new ‘perfect storm’ of rare space weather with high possibility of radiation.

Over time, the sun has been releasing powerful flares, emissions of electromagnetic radiation, which contain large quantities of charged particles that have accelerated in speed and increased in number due to the intense magnetic activity on the star’s surface.

And now the National Oceanic and Atmospheric Administration (NOAA) shows a 60 percent chance of a solar ‘radiation storm’ starting tomorrow with a lower possibility on Wednesday as well.

The particles can interact with planet’s magnetic field and atmosphere, causing disruptions to satellite communications, as well as radiation hazards for astronauts in space and interference with power grids.

While the next few days of these solar storms are predicted to miss the planet, the radiation storms are expected to launch their highly charged particles into a curved magnetic field, the Parker Spiral, which curls out of the sun into the solar system.

As the sun rotates, the magnetic fields that emanate from it bend as they flow passed the planets in its orbit, creating a spiral structure known as the Parker Spiral.

Charged particles from a solar flare can become caught in these spirals, shooting them around back to earth — when they would have otherwise missed the planet.

The magnetic storm on the sun that is responsible for these events is still producing the most intense class of solar flares, X-class flares, NOAA forecasters said Monday.

This week’s coming solar radiation storm differs from the ‘geomagnetic storms’ that hit Earth this weekend, which were a direct hit powerful enough to disrupt Earth’s protective magnetic field, the magnetosphere.

Much of the coming radiation storm will be absorbed by Earth’s magnetic field, but not near the exposed polar regions — where Earth’s magnetosphere curves back down and inward toward Earth’s core.

NOAA’s Space Weather Prediction Center also noted that the past weekend’s geomagnetic storms would persist until 5PM ET Monday, with the possibility of further, but weaker ‘power grid fluctuations’ and impacts on ‘satellite operations.’

The storm’s ability to push the famous ‘Northern Lights’ further south would also continue with aurora still likely to be visible along the ‘northern tier of the US such as northern Michigan and Maine,’ according to the agency’s space weather experts.

Then, as the week progresses, Sunspot AR3664, the giant ‘sunspot’ responsible for last weekend’s solar storms, is scheduled to pass through a portion of the Parker Spiral, curving its high-speed radiation onto a path intersecting with Earth’s orbit.

Sunspot AR3664, a dark patch of the sun’s surface with a magnetic field about 2,500 times stronger than Earth’s own, is one of the largest sunspots observed in decades.

The dense magnetic event is as long as 15 Earths and capable of producing solar storms on par with the 1859 Carrington event, which set telegraph stations and wires on fire, cut communications worldwide, and disrupted ships’ compasses.

Because Earth is now mostly out of range from any more direct hits from this roiling sunspot’s geomagnetic storms, this week’s radiation storms will come from a unique feature of the sun’s own rotation.

‘[As] the Sun rotates, the Sun’s magnetic field expands outwards in a spiral pattern, the Parker Spiral,’ according to NASA’s Solar Dynamics Observatory team.

When the ejections from a sunspot like AR3664 hits the right portion of the spiral, in the team’s words, it leads to ‘the charged particles of the solar wind spraying out into the solar system like a garden sprinkler.’

Already, NOAA’s space weather observing satellite GOES-18 has detected a surge in subatomic particles, specifically protons, ejected from the sun into Earth’s upper atmosphere.

GOES-18’s ‘proton radiation’ readings passed the ‘warning threshold’ midday Monday, in advance of the predicted ‘radiation storm’ later this week.
NOAA’s team issued a warning that radio communications at Earth’s poles could already experience ‘fades’ at certain frequencies today.

Last Friday, farmers in Minnesota, Nebraska, and other parts of the American Midwest experienced satellite disruptions to the ‘global positioning system’ (GPS) equipment that they depend on for operating their equipment.

‘All the tractors are sitting at the ends of the field right now shut down because of the solar storm,’ one farmer, Kevin Kenney, told 404 Media this weekend. ‘No GPS.’

‘We’re right in the middle of corn planting,’ Kenney added.

Many farms now use GPS to more efficiently and precisely plant crops in straight rows, reducing errors like overlapping seed beds or gaps of unused soil.

‘I’ve never dealt with anything like this,’ Patrick O’Connor, who owns a farm roughly a 90-minute drive south Minneapolis, told the New York Times.

O’Connor’s had hoped to plant his corn and soybean crops late Friday night, after rain conditions kept his operations in a holding pattern for two weeks — only to be thwarted by the solar storm.

The issue was so widespread this weekend that the maker of John Deere farming equipment, Landmark Implement, issued a text message warning across the Midwest, advising customers to turn off their equipment during the storm.

While the company reported that its agricultural GPS systems had been ‘extremely compromised’ due to the storm, they also voiced their opinion that the event was a rare one.

‘We are in search of [a] tool to help predict this in the future so that we can attempt to give our customers an alert that this issue may be coming,’ the company said in a statement.

‘We do believe this [is a] historic event and it isn’t something that we are going to have to continue to battle frequently.’
