The appearance of the northern lights in unexpected places, far from the Arctic Circle, where they are normally observed, can be attributed to a powerful geomagnetic solar storm that produced a significant flare of level X1,0 on the measurement scale. To fully understand this phenomenon, the convergence of solar radiation and the Earth's magnetic field played a crucial role. Experts suggest that in the coming days there is a possibility of another geomagnetic storm, which could have significant repercussions. These repercussions would be the direct result of a geomagnetic solar storm.
In this article we are going to tell you what the powerful solar storm of May 2024 was like and some of the repercussions that a solar storm may have.
Solar storm
While solar storms do not pose a direct threat to Earth, the impact of this phenomenon on current technologies can be significant and potentially disastrous. To better understand how these events affect Earth, you can check out our article on solar storms and its impact on technology.
Throughout the year 2024, our planet has been subjected to recurring solar events that have the potential to directly impact communication systems. However, The appearance of a geomagnetic storm requires a combination of multiple factors, including reaching maximum intensity and lasting for several hours. If you want to know more about the solar radiation levels on Earth, here you will find detailed information.
According to the SciTechDaily website, the Sun unleashed a powerful storm on May 12, registering a classification of X1.0. The storm peaked at 12:26 p.m. Eastern Time in the United States. The sun's AR3664 region, according to the National Autonomous University of Mexico (UNAM), is responsible for generating geomagnetic disturbances. To understand how these active regions are produced, we invite you to visit What would happen if a solar storm hit the Earth?.
Impacts of a geomagnetic storm
The impacts of a geomagnetic storm are:
- Interruption in water supply.
- Transportation systems experience major failures.
- Cases of technological failures in the digital field.
- The electrical service is damaged.
- The absence of water and electricity services
The most powerful solar storm in recorded history
It has been 165 years since the last appearance of a geomagnetic solar storm that could have catastrophic effects on Earth. However, during that period, technology had not yet assumed a fundamental role in human existence.
During the year 1859, the esteemed astronomer Richard Carrington had the extraordinary opportunity to observe a remarkable event: a dazzling eruption of white light emanating from the surface of the Sun, which in turn produced colossal flares of such magnitude that it was estimated that They were equivalent to the explosive force of 10 billion atomic bombs. To delve deeper into the phenomenon, you may be interested in our analysis of extreme solar flares.
The Carrington event, a powerful storm, caused the northern lights phenomenon to be observed around the world, including regions as far away as Cuba, Chile and Australia, although the limited technology of the time prevented significant consequences.
According to the center, the recent flare, classified as X8,7, marked the most severe geomagnetic storm since 2003. According to the center, A flare is an explosion of solar energy that typically lasts a short period of time, ranging from minutes to hours.To understand the dynamics of these flares, check out our article on what is solar maximum. It's worth noting that flares of this magnitude are rare.
The active regions of the Sun, which are characterized by strong magnetic fields, are where solar flares usually take place. These flares have the potential to disrupt radio signals, power grids, and communication systems. People who rely on high-frequency radio signals may experience temporary or even complete signal loss.
As a result of the Sun's rotation, the sunspot in question has diverted its energy from the Earth, thus reducing possible impacts. For more information on how solar radiation affects our planet, see the solar wind and its influence.
While flares have the potential to endanger astronauts and spacecraft, NASA recently determined that there was no danger to the crew aboard the International Space Station. To better understand how they protect space missions from these events, visit the secrets of Jupiter's atmosphere.
According to the Solar Dynamics Observatory at X, the Sun's activity follows a cyclical pattern known as the solar cycle, which extends over a period of 11 years. Solar cycle 2019 began in December 25 and is currently approaching its peak, also known as solar maximum. During this phase, events such as eruptions become increasingly frequent. To analyze the influence of the solar cycle on storms, we recommend consulting How solar minimum will affect Earth.
Recommendations
Not only that, but solar particles also raise radiation levels in the upper regions of the atmosphere, potentially endangering the well-being of astronauts and damaging satellite technology. Consequently, they also produce notable visual phenomena.
To effectively navigate and weather an exceptionally powerful solar storm, it is essential to make advance preparations and implement precautionary measures. National Geographic has provided a comprehensive guide outlining several strategies to effectively manage and mitigate the impact of such events.
- Stay well-informed and up-to-date with space weather alerts and forecasts disseminated by accredited agencies such as NOAA and other comparable organizations. These valuable alerts provide advanced insights into potential solar storms.
- Create a comprehensive emergency plan for your home and your loved ones, outlining the necessary steps to take in the event of a severe solar storm. It is essential that all members of your family are well informed about the plan and fully equipped to implement it effectively.
- To ensure effective communication during a solar storm, It is essential to have backup options, such as shortwave radios or CB radios (CB), as cell phone and Internet networks may suffer interruptions. Additionally, it is advisable to have a stock of non-perishable food, drinking water and essential medicines that can sustain you for a minimum of two weeks, as prolonged power outages can potentially disrupt the availability of essential goods.
- To ensure uninterrupted power supply, It is advisable to purchase a portable generator and keep its charge for immediate use.. To protect electronic devices from the impact of solar storms, it is recommended to use surge protectors as a protective measure.
- To ensure financial stability During power outages or communications interruptions, it is advisable to have physical cash available, as electronic transactions and ATMs may be affected.
