The Jeddah Astronomical Society announced that its specialized satellites a moderate solar flare emanating from the active sunspot designated “AR3697” (referred to in the source as 4455). This astronomical event, classified as an M3.3 flare, raises the possibility that it may be accompanied by a coronal mass ejection (CME) that could be directed towards Earth, potentially causing a minor geomagnetic storm in the coming days.
Understanding solar activity phenomena
The Sun is a perpetually active star, undergoing cycles of activity that peak approximately every 11 years. During these periods, sunspots become more frequent. Sunspots are temporarily cooler regions on the Sun's surface characterized by strong and complex magnetic fields. When the lines of these magnetic fields tangle and erupt suddenly, they release enormous amounts of energy in the form of solar flares and coronal mass ejections (CMEs). Flares are classified according to their intensity into categories A, B, C, M, and X, with M being moderately intense and X being the most powerful. A coronal mass ejection is a massive cloud of plasma and magnetic field ejected from the Sun. When it travels toward Earth, it can interact with our magnetosphere, causing what are known as geomagnetic storms.
Potential effects of a magnetic storm on Earth
The head of the Jeddah Astronomical Society, Engineer Majed Abu Zahra, explained that if this emission reaches Earth and its trajectory is confirmed, it could lead to a G1-level geomagnetic storm. This level is the lowest on the scale of geomagnetic storm intensity, and its effects are usually minor and localized to specific areas. These effects may include minor disruptions to power grids at high latitudes, slight impacts on satellite operations, and the possibility of intermittent interference with radio communication and high-frequency navigation systems. The most beautiful effect of these storms is the aurora borealis (northern lights), which is more likely to be seen in areas near the Arctic and Antarctic Circles.
Why is the Arab world not affected by this average solar flare?
Abu Zahra confirmed that Arab countries, due to their geographical location at low and mid-latitudes, are not expected to be directly affected by this solar activity. The Earth's magnetic shield is very strong in these regions and is capable of deflecting most of the charged particles coming from the sun. Therefore, the potential storm level (G1) is not sufficient to cause noticeable effects on the technological infrastructure in the Arab region, nor will it allow for the appearance of the aurora borealis in its skies. Observatories and space weather centers around the world continue to analyze data received from satellites to determine the speed and direction of the coronal mass ejection more accurately and to assess its potential impact on the space environment surrounding Earth upon its expected arrival.
