Sun covered
Sun position at maximum
The Sun will be 66.2° above the horizon at an azimuth of 22°. This helps when choosing an unobstructed viewing direction.
How to read the map
- Magenta shading marks the approximate area where at least a partial eclipse may be visible. Darker bands mean a larger percentage of the Sun is covered.
- The solid band is where the eclipse becomes annular; the dashed centre line is usually near the longest central phase.

The eclipse city by city
Local times, coverage and where to look for each place.
Where the ring of fire is visible
The path of annularity comes ashore in southern Chile around Chiloé, crosses Argentine Patagonia between Esquel and Viedma, and leaves the coast near Mar del Plata before clipping Uruguay around Punta del Este. It then crosses the South Atlantic and ends at sunset on the Gulf of Guinea coast.
The longest ring, 7 min 51 s, happens over the open ocean. On land, the Argentine coast near Mar del Plata gets about seven and a half minutes. Buenos Aires, Montevideo and Santiago lie outside the path and see a partial eclipse, with roughly 60 to 85% of the Sun covered.
What to expect on the day
In Patagonia the eclipse peaks around midday, with the summer Sun high in the northern sky, so nearby buildings and trees are less of a problem than at most eclipses. In West Africa the ring forms just before sunset: in Accra the Sun is only about 4° above the west-south-western horizon at maximum, so you need a flat, open view in that direction.
An annular eclipse never gets dark. Even at its deepest, about 14% of the Sun’s disc stays uncovered, which is far too bright to look at. Keep eclipse glasses on for every phase, including the ring.
Viewing safely
Except during the brief total phase of a total solar eclipse, never look directly at the Sun without suitable solar viewing protection. Eclipse glasses should comply with ISO 12312-2. Cameras, binoculars and telescopes need purpose-made filters fitted over the front of the optics.

What time is the eclipse on 6 February 2027?
The eclipse peaks at 3:59 PM UTC. Local times depend on where you are: in Mar del Plata, the ring of fire begins at 12:24 PM and ends at 12:31 PM local time.
How long does the ring of fire last?
Up to 7 min 51 sec near the point of greatest eclipse. Places inside the path see less, and the phase lasts longest near the centre line. In Mar del Plata it lasts about 7 min 30 sec.
Will the eclipse be annular in Buenos Aires?
No. Buenos Aires is outside the path and sees a partial eclipse, with about 82% of the Sun covered at 12:31 PM local time.
Will the eclipse be annular in Santiago?
No. Santiago is outside the path and sees a partial eclipse, with about 62% of the Sun covered at 12:04 PM local time.
Is the February 2027 eclipse total?
No. It is annular: the Moon is too far from Earth to cover the whole Sun, so a thin ring stays visible. Inside the path the light dims noticeably, but the sky does not go dark as it does during totality.
