A potential geomagnetic storm due to a solar flare and astronomical observation in Jeddah

0 1 One minute

The Jeddah Astronomical Society revealed that specialized solar monitoring satellites have detected a moderate solar flare, which could lead to a geomagnetic storm in the coming days. The society's president, Engineer Majid Abu Zahra, explained that this flare, observed on June 2, 2026, originated from active sunspot 4455, and is expected to be accompanied by a coronal mass ejection (CME) heading towards Earth.

Preliminary data and available astronomical analyses indicate that this solar flare ejected enormous quantities of plasma and magnetic fields into outer space. However, satellite imagery has not yet definitively confirmed whether this coronal mass ejection is on a direct, full-scale collision course with Earth, or whether it will pass alongside the planet's magnetosphere.

Classification of solar storms and probability of a geomagnetic storm

Engineer Majed Abu Zahra added that confirmation of this coronal mass ejection reaching Earth could result in a geomagnetic storm . This level is the lowest and weakest on the five-level scale of geomagnetic storm intensity (from G1 to G5). Historically, the Sun undergoes activity cycles lasting approximately 11 years, during which the frequency of sunspots and flares increases. G1-level storms are a very frequent and common occurrence during the peak of these solar cycles and do not warrant concern or any extraordinary measures.

Expected impacts on global technology and communications

Globally, the effects of weak geomagnetic storms are typically limited to minor and very limited disruptions to electrical power grids and GPS navigation systems, as well as slight interference with some high-frequency radio frequencies used in aviation and maritime navigation. This astronomical phenomenon also contributes to the appearance of the mesmerizing aurora borealis (northern lights) in the skies near the Arctic and Antarctic Circles, where charged particles from the sun interact with Earth's atmosphere.

Are Arab countries affected by the recent solar activity?

Regarding the regional and local impact, the head of the Jeddah Astronomical Society reassured citizens in the Arab region, emphasizing that Arab countries will not be directly affected by this solar activity. This is due to the geographical location of the Arab world, situated in low and mid-latitudes, areas largely protected by the Earth's magnetosphere against this type of weak storm. Furthermore, the expected storm's intensity will not be sufficient to produce the aurora borealis in the skies of the Arab region. Global observatories and space weather centers continue to analyze incoming data to accurately determine the emission speed and assess any emerging developments.
