A spectacular and rare annular solar eclipse is scheduled for February 6, 2027, offering a true celestial spectacle for observers positioned in parts of América of Sul, Europa and África. The astronomical event stands out for its duration and the clarity with which the phenomenon can be seen in different locations, attracting the attention of scientists and enthusiasts from all over the world.

The highlight of the eclipse will be the formation of the famous “ring of fire”, a visual effect that occurs when Lua aligns perfectly between Terra and Sol. However, because it is at a more distant point in its orbit, the lunar disk will not completely cover Sol, leaving a bright solar edge visible, similar to a luminous ring in the sky.

The trajectory of the 2027 eclipse is vast, starting at Oceano Pacífico and touching the South American continent at Chile and Argentina. It will then cross the Oceano Atlântico to reach the south of the Espanha and travel a long stretch through the north of the África, passing through countries such as Marrocos, Argélia, Tunísia, Líbia and

What defines an annular solar eclipse

Unlike a total solar eclipse, where the Lua completely blocks the light from the Sol for a few minutes, the annular eclipse occurs due to a particularity in the lunar orbit. Lua rotates around Terra in an elliptical path, which means that its distance from our planet varies. Quando the eclipse occurs with the Lua close to its furthest point, known as apogee, its apparent size in the sky is smaller than that of the Sol.

Essa difference in size prevents the star from completely blocking, resulting in the formation of the ring of sunlight around the dark silhouette of Lua. Para the 2027 event, the magnitude of the eclipse will reach 0.928, which means that Lua will cover around 93% of the solar disk at the maximum point of the phenomenon. This configuration will provide a well-defined and visibly bright “ring of fire”, requiring special eye protection to observe during all phases.

Trajectory and main points of visibility

The “ring of fire” journey will begin at dawn over Oceano Pacífico, making its first contact with land in southern Chile and in the province of Santa Cruz, in Argentina. Nessas locations, the Sol will already be eclipsed, providing a unique view of the phenomenon at low altitude on the horizon.

After crossing Atlântico, the shadow of Lua will reach Europa around local noon, with the annular band passing through the southern tip of Espanha. Cidades in the Andaluzia region, like Cádiz and Málaga, will be in privileged positions to observe the eclipse in its fullness, making the region one of the points of greatest interest for European observers.

The longest and most prominent phase of the eclipse will occur over northern África. The visibility range will cross Marrocos, northern Argélia and central Tunísia. The route will continue through Líbia and Egito, where the duration of the “ring of fire” will reach its maximum, providing an extended observation window and favorable weather conditions.

The event will come to an end in the late afternoon, with the shadow passing over the city of Meca, on Arábia Saudita, and dissipating over Oceano Índico. The partial visibility of the eclipse, where Sol appears only “bitten” by Lua, will be much wider, covering almost all of América, Sul, África,

Record duration of the phenomenon

One of the most notable aspects of the 2027 eclipse is its long duration. At the point of greatest annularity, located near the historic city of Luxor, at Egito, the “ring of fire” will remain visible for an impressive 7 minutes and 53 seconds. Essa duration is exceptionally long for an annular eclipse and positions this event as the longest of its kind since 1992 and the longest of the 21st century. The long observation window is the result of a precise combination of orbital factors, including the speed of Lua’s shadow on Terra’s surface and the relative distances between the three celestial bodies. Essa feature not only intensifies the experience for the public, but also provides a valuable opportunity for the scientific community to conduct detailed studies of the solar atmosphere, such as the chromosphere, which becomes more accessible for analysis during the phenomenon.

Best places for observation

Choosing the ideal location to observe the eclipse depends on a combination of factors, including the duration of the annularity and expected weather conditions. The south of Espanha, in the Andaluzia region, is an attractive option due to its tourist infrastructure and accessibility, although the chances of clear skies are moderate for the time of year.

North of África, on the other hand, offers the best chances of favorable weather. Tunísia, especially in places like the island of Djerba, and Egito, in the region of Luxor, are considered first-rate destinations. Luxor, in particular, combines the eclipse’s maximum duration with a historical setting, allowing observers to witness the phenomenon over ancient temples and monuments.

In América of Sul, the Argentine region of Patagônia, despite presenting the challenge of observing the event close to sunrise, promises spectacular images with the “ring of fire” forming over impressive natural landscapes. The low altitude of the Sol can create unique photographic effects for the more adventurous.

How to observe the eclipse safely

It is essential to emphasize that observing an annular solar eclipse requires strict care to protect your vision. Olhar directly to Sol, even for a few seconds, can cause permanent damage to the retina. Durante all phases of an annular eclipse, including the moment of the “ring of fire”, the use of adequate eye protection is mandatory.

Safe methods include using internationally certified ISO 12312-2 eclipse glasses or high-quality solar filters designed for telescopes and binoculars. It is crucial to check that the filters are not scratched or damaged before use. Indirect projection Métodos, such as building a darkroom with a cardboard box (pinhole projector), are safe and affordable alternatives for viewing an Sol image without risk.

Scientific and tourist interest for the event

Astronomical events of this magnitude generate great interest in both the scientific community and the tourism sector. Espera There has been a significant increase in “astro-tourism” in regions that are on the eclipse’s main route, with enthusiasts traveling from different parts of the world to ensure the best view. Cidades like Luxor and tourist destinations in Espanha and Tunísia are already preparing to receive a large number of visitors.

For scientists, the long duration of the “ring of fire” will allow prolonged studies of the solar chromosphere, the reddish layer of the Sol atmosphere visible just above the photosphere. Além In addition, the event makes it possible to calibrate space instruments and carry out experiments on the Earth’s ionosphere, which is directly affected by the variation in solar radiation during the eclipse.

Notable Upcoming Celestial Events

The 2027 annular eclipse is part of a series of notable solar events that will occur this decade. Antes of it, on August 12, 2026, a long-awaited total solar eclipse will be visible in full in a band that crosses Groenlândia, Islândia and the north of Espanha. Este will be the first total eclipse to occur on the continental Europa since 1999, promising to draw large crowds to the region.

Later, on January 26, 2028, another annular solar eclipse will occur. Sua trajectory will pass through América of Sul, being visible in parts of Equador, Peru and north of Esses consecutive events reinforce a period of intense celestial activity, offering multiple opportunities for the observation and study of solar phenomena.
