The physics of solar phenomena such as coronal mass ejections have not been studied in detail, but evidence suggests that they are magnetic in nature and occur about every 11 years. What are the risks to Earth from today’s event?

July 11, A solar flare caught the attention of personnel at space observatories around most of the world. This phenomenon, which normally occurs in the Royal Star’s atmosphere, consists of a sudden burst of electromagnetic radiation and energetic particles from a small area of ​​the Sun’s atmosphere. She came from a region of the sun where its magnetic field is particularly strong and complex, causing these explosions to propagate at the speed of light.

However, these phenomena do not always occur spontaneously, but are the result of a much larger process, like the one the sun is experiencing right now.

Inside the Astro-King, the same magnetic field that caused the explosion observed on July 11 continued to twirl and twirl, hurling massive amounts of solar plasma into space. This process, known as coronal mass ejection (CME), moving slower than ejecta, and that’s what’s been happening for the past week.

On July 15, one of them was catapulted to earth from the sun and Despite its slower speed, projections from NOAA’s Space Weather Prediction Center suggest so that it will reach Earth this Thursday, July 21st.

How could this phenomenon affect telecommunications?

The physics of these solar phenomena (solar wind, sunspots, solar flares and coronal mass ejections) have not been studied in detail, but there is every reason to believe that they are mainly magnetic in nature. and occur about every 11 years. Then the sun experiences its most active magnetic periods, called solar maxima, where the frequency of these events is particularly high.

And right now the sun is nearing the peak of its current cycle, expected to peak in 2024 as an increasing number of these phenomena have been recorded in the Earth’s upper atmosphere since last fall (2021).

A coronal mass ejection can affect the Earth in several ways: although it is often accompanied by auroras (and is also commonly visible at high latitudes such as northern Michigan and Maine), its interaction with the Earth’s magnetosphere can lead to compression and change in its structure, Creating new, more complex magnetic fields in addition to the Earth’s existing magnetic field.

geomagnetic storm
The effects of a geomagnetic storm are felt in the form of disruptions to satellites, GPS, and other telecommunications systems.

This phenomenon is called a geomagnetic storm and its effects are felt in the form of interference with radio and satellite communications, as well as power outages in the most extreme cases.

The good news in this NOAA forecast is that according to estimates this geomagnetic storm will be at the lowest level, level 1, and can occasionally cause fluctuations in the power grid and hardly affect the operation of terrestrial satellites. Finally, on this plane and on higher planes, Draft animals may be affected. However, it does not pose a risk to public health.

A look into history

While it’s not the most intense episode ever, it’s still good to take a look back at history. The year 1859 is remembered as a time leading up to the Carrington Incident: that year, A large geomagnetic storm of the same origin caused the failure of telegraph networks in Europe and North America. He also set receivers on fire and caused multiple electrocutions in a world not yet as dependent on telecommunications as it is today.
