Geomagnetic Storm May Continue Today

A strong geomagnetic storm, originating from a recent solar flare, may continue today, although with reduced intensity. According to astrophysicist Stelios Tsanggaridis, this phenomenon is a natural "attack" on the Earth's magnetic field, caused by the ejection of charged particles from the Sun. The Earth, due to its distance and size, is usually protected from the solar wind, as its magnetic field deflects the particles towards the poles, creating the spectacular Northern and Southern Lights. However, in rare cases, such as the current one, strong solar winds can penetrate the magnetic field and reach the Earth's surface. Geomagnetic storms are categorized from G 1 (weak) to G 5 (extreme), and the most severe can disrupt power grids, affect voltage in homes and businesses, and interrupt communications via satellites. Mr. Tsanggaridis emphasized that a prolonged geomagnetic storm could jeopardize technology and have serious consequences for human life. Therefore, it is important for competent authorities to take preventive measures to protect infrastructure and the population. The phenomenon has already been recorded in Cyprus with the appearance of the Northern Lights, a rare sight that testifies to the intensity of the geomagnetic storm. Monitoring the situation and taking the necessary safety measures are crucial to address the potential impacts.
