Forecasters predict a ‘weak’ solar storm will hit Earth
Solar storm expected to hit Earth
As material flows out of a hole in the Sun, a solar storm could be on its way to Earth. According to the US National Oceanic and Atmospheric Administration, the G1 storm could cause power outages, disrupt satellites, and disrupt animal migrations. Nonetheless, they are minor compared to the much more dramatic effects that can occur during geomagnetic storms. Strong solar winds are expected to batter the Earth's geomagnetic field tomorrow, potentially causing power grid fluctuations, communications interference, and aurora over the US states of Maine and Michigan. The solar storm is expected to hit Earth around the same time as the end of the year. The storm is expected to be the most powerful of the year. The last major solar storm that hit Earth was in 1859. Forecasters at the US National Oceanic and Atmospheric Administration (NOAA) issued the warning, stating that the Earth is about to pass through a high-speed solar wind stream. Spaceweather.com says this phenomenon is caused by "gaseous material flowing from a southern hole in the Sun's atmosphere." Such "coronal holes," which appear as dark areas in extreme ultraviolet and X-ray images, are areas where the Sun's plasma is more relaxed and less dense than that around it, due to the star's magnetic field extending out into space as an open field.
Coronal holes can be thought of as high-speed solar winds. "Solar wind exiting a coronal hole travels much faster, reaching speeds of up to 500 miles per second. When these solar wind particles reach the earth, which can take two to four days depending on their speed, they can cause minor geomagnetic storms. High-speed wind gusts can also cause problems for satellites in orbit "according to the Exploratorium, a science museum in San Francisco. 'The solar wind is a stream of charged particles that are created when the sun's magnetic field interacts with the solar atmosphere,' the Exploratorium website says.
According to NOAA, the geomagnetic storm caused by Earth's encounter with the stream of solar wind will be minor, classified only as a G1 event. This is the smallest of the five G-scale categories used to classify geomagnetic storms. Tomorrow's storm, as a G1, has the potential to have minor effects on satellite operations and cause minor fluctuations in the power grid. G5 events, on the other hand, could have a significant impact on satellite operations, cause surges that knock out power grids, and disrupt high-frequency radio communications for days on end. Fortunately, G5 solar storms occur only about four times every 11-year solar cycle. The next expected G5 event is expected to occur in 2023. (Solar Cycle 24 is currently in progress. The next solar maximum is expected to occur in 2029.)
Space Earth to be hit by solar storm after hole opens in the Sun
The generation of auroras at lower-than-usual latitudes is another likely outcome of tomorrow's geomagnetic storm, with experts predicting that such displays will be visible over both Maine and Michigan in the United States. Auroras are natural light shows that occur when solar wind particles excite atoms in Earth's upper atmosphere, causing them to glow. The aurora forms curtains of light that follow the geomagnetic field lines and appear in various colors depending on which atoms are excited. The two main gases in the Earth's atmosphere are oxygen, which emits a greenish light, and nitrogen, which emits blue, pink, and purple light. The aurora borealis, or northern lights, are named for the northernmost part of the aurora borealis. The aurora australis, or southern lights, are named for the southernmost part of the aurora borealis. The aurora borealis is visible over the North Pole, while the aurora australis are visible over the South Pole. The aurora australis is also known as the southern lights, or the aurora australis, or austral aurora.
Heaven and Earth
The Carrington Event is the name given to the most powerful geomagnetic storm ever recorded, which occurred in September 1859. Rather than being caused by Earth passing through a high-speed stream of the solar wind, it was caused by a Coronal Mass Ejection. These occur when the Sun spews a cloud of charged particles and electromagnetic fluctuations into space. The Carrington Event had an impact on telegraph networks throughout Europe and North America, as well as the recently laid transatlantic link that linked them. It was the first time a geomagnetic storm was observed to interfere with telegraphic communications. The storm caused telegraph lines to spark, electric shocks to operators, and some lines to fail.
A solar storm could cause both auroras and electrical problems
Space weather event currents reportedly caused telegraph pylons to spark, operators to receive electric shocks, and some lines to fail. Other connections, meanwhile, were discovered to be still operational even after their power had been cut, owing to the strong electrical currents induced by the storm. The storm was so powerful that it was able to knock out power to the entire state of Florida. Unlike Victorian-era telegraph lines, the fiber optic cables that form the Internet's backbone are not affected by electromagnetic fluctuations caused by solar storms. However, the same cannot be said for the signal boosters installed along undersea cables to maintain connections over long distances.
Because these long-distance cables are underwater, they are not only more vulnerable to the effects of space weather, but they are also more difficult to access for repairs. Astrophysicists predict that a solar storm powerful enough to cause catastrophic disruption to modern society will strike the Earth within the next ten years. The best way to protect against such an event is to have an effective communications network in place, and the best way to ensure communications protection is to use sources that are as resilient as possible.
