The U.S. National Oceanic and Atmospheric Administration (NOAA, for its acronym in English) warned about this Monday Geomagnetic storm caused by a large amount of sunlight affecting the Earth today and creating interruptions in power networks, It can carry hundreds of miles of northern lights up to New York City.
What is the eventAn extension known to experts as “coronal mass ejection” (CME) and the side of the sun facing the Earth was observed by astronomers on Saturday. CMEs occur during periods of greatest solar activity.
The place of the sun Active AR2882 erupted on Saturday October 9, 2021 (0640 UT), Creates strong M1.6-class sunlight and earth-driven CME
The NOAA’s warning highlighted it Geomagnetic storms create fluctuations with voltage alarms at higher latitudes in the electrical network because the earth is more exposed in these areas.
What else, Satellites can be vulnerable and show “orientation irregularities” They must therefore be diverted from ground controls so that any object in low Earth orbit experiences increased resistance. The U.S. state agency said the magnetic storm could reach Type G2, which is moderately strong.
“The event analysis and sample departure recommends the CME arrival at noon on October 11, with continuous effects lasting until October 12,” NOAA said. It takes place in the UK and Europe from afternoon to evening, i.e. in Argentina and South America until noon and afternoon.
“Aurora has a small chance of reaching the UK and Ireland tonight, but so the clouds are breaking Vision is high in Northern Ireland “, The company added.
It is mostly visible at high latitudes in the south and north of the earth. That is, if the conditions are right, you can see them in such places Tasmania, Scotland, southern Sweden and the Baltic states.
The polar aurora is an atmospheric phenomenon that appears in the form of brightness or glow in the night sky, usually in the polar regions, which may appear for short periods in other parts of the world. In the Northern Hemisphere it is known as the Aurora Borealis and the Southern Aurora Astralis.
The largest solar storm was reported 1859 and is called the Carrington event, but according to forecasts it will not reach a similar magnitude.
The Carrington event caused an aurora to be seen in the sky even at latitudes very close to the equator and described in contemporary reports Brighter than the light of the full moon.
That solar storm This led to failures in telegraph systems throughout Europe and North America, and later became the most important means of telecommunications. If a similar event occurs today, it is estimated that it will cause billions of dollars in damage worldwide.
Astronomers say Solar activity increases and decreases every 11 years. This is a natural phenomenon, however it does not work with extreme accuracy. Experts point out that the Earth is in the early years of a new period of activity.
Scientists say the sun may have risen during increased sunlight activity, After being relatively quiet for the past few years. A new family of sunspots was discovered on the surface of the star, triggering the largest amount of sunlight they have seen since 2017.
There are different types of solar flares. Tenth grade is considered very serious. CME, which occurred on Saturday, is an M-class event, the second strongest after X. This is called “hollow CME” because the flames heading towards the earth look like a halo around the sun.
