NASA scientists announced the impact of a new geomagnetic storm against the earth between March 23 and 25 due to the appearance of a coronal hole in the south of the sun’s outer atmosphere.
NASA’s Solar Observatory noted a black spot on the sun about 300,000 kilometers across, or about 30 planets the size of Earth. The sunspot caused the release of winds composed of ions and electrons that, according to the latest readings, are already hitting our planet.
The National Office of Oceanic and Atmospheric Administration (NOAA) established a scale of intensities to calculate the risks of solar storms. Each solar outflow is classified into five possible levels, from G1 to G5. The storm that is already on Earth is considered G1 level, although at its peak of activity it could reach G4.
Coronal holes like the one NASA recently found are common and part of the solar cycles that occur every 11 years. Humanity has studied them for a long time and, although the origins of the phenomenon are not entirely clear, it has been concluded that they are less risky than other stellar phenomena such as coronal mass ejections and solar flares.
Will there be consequences of the geomagnetic storm announced by NASA?
Like any expulsion of solar wind that reaches Earth, in the most recent there will be physical manifestations that some humans will be able to perceive directly or indirectly. At the G1 and G2 level, the consequences are from variations in the electrical network, alterations in GPS systems, minor failures in telecommunications and, of course, many auroras boreales in northern countries such as Canada, Alaska, Russia, Norway, Greenland or Scotland.
For cases of G4 geomagnetic storms, classified as ‘serious’, NOAA recommends paying special attention to theThe activities of satellites that are in low earth orbit and in the air traffic of planes and helicopters.
There is no scientific evidence linking geomagnetic activity and any symptom of affectation in humans or any other living system. The affectations, if they occur, are exclusive to electrical systems.
In 1859 humanity experienced the biggest storm on record. The solar winds were so powerful that northern lights were recorded in countries like Cuba and Honolulu. Around this time, the greatest technological advance, the telegraph, collapsed and according to newspaper accounts, the lines became so hot that they were melting and sparking.
Until now, scientists have accepted that there is no way to protect the planet from a geomagnetic storm, neither light nor strong, so that, if one of larger proportions occurs, it could cause unprecedented economic and social problems.
