The Emirates Astronomical Society announced that the whole world observed yesterday and today a giant and distinctive sunspot that appeared on the disk of the sun and was seen with the naked eye minutes before sunset and can be seen during the next two days, calling for not looking at the sun directly with the naked eye during the day.
She explained that sunspots are spots on the surface of the sun – the photosphere – and are characterized by a lower temperature than the surrounding areas and intense magnetic activity that prevents the transfer of heat, forming areas with a low surface temperature..
Ibrahim Al Jarwan, Chairman of the Board of Directors of the Emirates Astronomical Society and member of the Arab Union for Space and Astronomy, said: “This phenomenon occurs with the presence of coronal solar activity, explosions, and the launch of coronal mass projectiles from the sun’s corona. The center of sunspot activity develops in several stages, starting with the formation of a normally attached dipole magnetic field.” With the sudden appearance of a small bright spot called a flame, which is known as luminous gas clouds composed mainly of hydrogen and located slightly above the visible surface of the sun..
He pointed out that these black spots that are located on the surface of the sun have various shapes and said: “If we continue to monitor them day after day, we will find that they move on the surface of the sun, but this in fact indicates the rotation of the sun around itself, and sunspots form over periods extending from days to weeks, and they can It extends for months, and the maximum solar energy or maximum solar energy is considered the period of greatest solar activity in the sun’s solar cycle, as the duration of one solar cycle is about 11 years..
He added: “It is possible for the sun to contain hundreds of sunspots during periods, and it is possible for it not to contain any of them during other periods. This is due to the fact that these spots have cycles that occur over 11 years, and statistics have begun to show an increasing curve in the number of sunspots that are expected to occur.” Their number increases over time, reaching their peak in 2025 and 2026.”
Al-Jarwan pointed out that the absence of the most important features of the sun’s surface, which are sunspots, is the most prominent evidence of the weakness of solar activity, which means a decrease in temperature and that the Earth is vulnerable to an ice age such as the one that occurred in the period from 1645 to 1715, when sunspots continued to disappear for approximately 80 years or the equivalent. 7 consecutive solar cycles.
