Significant solar activity... and scientists are monitoring its impact on Earth.
This morning, Saturday, a noticeable increase in solar activity was observed, as the sun's disk appeared studded with a large number of sunspots. There are at least 10 groups of sunspots on the side facing Earth, including three new dark cores that began to appear at the eastern edge of the sun. This sudden increase in the number of sunspots reflects an active phase of the solar cycle and naturally leads to an increased likelihood of strong solar flares. These flares are phenomena that can be terrestrial in nature, meaning they are capable of affecting the Earth's magnetic field and the associated disturbances in space weather. According to the Jeddah Astronomical Society, sunspots are relatively cooler regions on the Sun's surface, associated with intense magnetic activity. When these magnetic fields interact suddenly, they can release enormous amounts of energy in the form of flares or coronal mass ejections, which can reach Earth within days. Engineer Majid Abu Zahra, head of the Jeddah Astronomical Society, said that experts warn that an increase in the number of these groups means a higher chance of strong flares that could affect communication systems, satellites, and power grids, especially if they are directed directly towards Earth. He added: Increased solar activity may have an indirect impact on the Artemis 2 mission, which is expected to launch in early April 2026, as an increase in the number of sunspots raises the likelihood of solar flares and storms that could pose a radiation risk to astronauts outside the protection of Earth's magnetic field.
However, this does not necessarily mean postponing the mission, as NASA relies on careful and continuous monitoring of solar activity and has the ability to adjust the launch timing if there are indications of dangerous activity, which ensures the safety of the crew and reduces potential risks.
It is worth noting that the American space agency NASA is preparing for a new attempt to launch its manned lunar mission, Artemis 2, during next April, in a step that is considered one of the most important stages of the human return to the moon after more than half a century since the last manned journey. This attempt comes after a series of technical delays that the rocket and spacecraft faced during previous tests. An opportunity to observe the aurora borealis
Abu Zahra added that, on the other hand, these conditions provide a unique opportunity to observe the aurora borealis in wider areas than usual, in the event of strong geomagnetic storms. The head of the Jeddah Astronomical Society added that he does not expect this solar activity to have a direct impact on daily life in the Arab world, as most solar flares pass without people noticing them. However, limited and indirect effects may appear in the event of strong flares directed towards Earth, such as temporary disruption to satellite navigation systems or wireless communications.
The effects rarely extend to electricity grids, and thanks to modern monitoring and protection systems, these effects mostly remain under control and do not pose a cause for concern, which means that daily life continues normally despite the increasing number of sunspots. Meanwhile, scientists continue to closely monitor the development of these sunspots to assess the likelihood of their increase in the coming days and determine their potential impact on planet Earth.
