In recent days, experts have observed intense solar activity, marked by large sunspots, eruptions and coronal mass ejections (CME) towards Earth. The expectation was that strong geomagnetic storms would occur on Tuesday (13), but so far nothing has happened.
It all started on February 7th, with the detection of a sunspot 15 times bigger than Earth, generating significant explosions that disrupted radio communications and released clouds of particles in our direction. The Sun remained active, with nine notable explosions recorded on February 12, some close to reaching the X rating, the most intense.
Three CMEs were forecast for February 13, capable of triggering class G1 to G2 geomagnetic storms, with the potential for aurora borealis in some regions. However, only one CME was recorded on the target date, with a weak impact. More recently, two CMEs were detected on the opposite side of the Sun, with no possibility of affecting Earth immediately, but models suggest they might still arrive.
NASA observed the second largest solar flare in years on February 9, causing disruptions to radio communications in several regions. There are concerns regarding the possibility of solar storms affecting the internet globally in 2024, leading to a collapse of communications systems.

Solar storms are result of the sudden release of energy stored in the Sun’s magnetic fields, It can last minutes or hours. These explosions release enormous amounts of energy, comparable to millions of volcanic eruptions on Earth. When these explosions occur in active magnetic regions of the Sun, they have the potential to impact the Earth, interfering with its electromagnetic field and posing risks to the internet and telecommunications.
In 1859, the largest solar storm ever recorded occurred, mainly affecting telegraph systems and places with electrical energy. Today, with increasing dependence on technology, a similar solar storm would have catastrophic impacts on global electronic devices.
Although the year 2024 is being marked by intense solar activity, there is no guarantee that extreme solar storms capable of causing significant damage to electronic devices will occur. Solar behavior is still poorly understood, and more studies are needed to accurately predict such events.
