An annular solar eclipse is occurring on Tuesday, February 17, 2026, a spectacular astronomical phenomenon in which the Moon, in its new moon phase, passes in front of the Sun and covers about 96% of its disk. This results in a bright circle around the star, commonly called the "ring of fire." According to the City of Sciences, this eclipse primarily concerns the southern hemisphere and will only be visible to a small portion of the global population. The phenomenon will occur mainly over isolated regions of Antarctica, while certain areas of South America and southern Africa will be able to observe a partial eclipse. Although the event is not visible in Tunisia or Arab countries, its occurrence on February 17, 2026 - corresponding to 29 Sha'ban 1447, the traditional day for observing the lunar crescent announcing the beginning of Ramadan - holds particular significance. The eclipse occurring at 1:00 PM (Tunis time) means that astronomical conditions make it scientifically impossible to spot the lunar crescent at sunset on that day. The City of Sciences also reminds us that Tunisia will be affected by a partial eclipse at sunset on August 12, 2026. More importantly, the country will be among the privileged zones for observing the total eclipse on August 2, 2027, dubbed the "eclipse of the century." Thanks to its geographical position, Tunisia will offer particularly favorable observation conditions. The phenomenon will occur over most of the territory between 9:00 AM and 11:30 AM, when the Sun will be at a moderate height above the horizon, making it easier to observe with specialized instruments or the naked eye using adapted protection. With a duration of totality that can reach approximately six minutes - among the longest in the world - Tunisia is expected to become a major destination for astronomy enthusiasts and scientists, particularly for the study of the solar corona.
