Sun Annular Solar Eclipse2027-02-06UpcomingNASA Saros 131

Annular Solar Eclipse of 2027-02-06

Annular path crosses central Chile and Argentina including parts of Patagonia, then sweeps the South Atlantic. One of the longer annular eclipses of the decade.

One of the longest annular eclipses of the 2020s at 7 minutes 51 seconds maximum annularity. Saros 131 produces these long annulars near aphelion.

Observation and photography

Every phase of a solar eclipse outside of totality requires ISO 12312-2 certified solar viewing glasses or an equivalent solar filter on every optical instrument (telescope, binoculars, camera lens). The same standard applies to annular solar eclipses. Glasses can come off only during the brief totality window on the central path; they must go back on the instant Baily's beads reappear at third contact.

Central-line duration is 7m 51s. A typical imaging plan brackets exposures from ~1/1000s for the chromosphere and Baily's beads down to ~2s for the outer corona, fired in a programmable sequence so the observer can watch with the naked eye for at least the middle third of totality.

Local sun altitude, the path crossing time of day, and recent weather climatology drive site selection. NASA's interactive eclipse map (linked below) gives the exact altitude and time for any coordinates on the path.

Frequently asked questions

Where will the annular solar eclipse of 2027-02-06 be visible?
The path of annularity crosses Argentina, Chile. Partial phases are visible from Argentina, Chile, Uruguay, Brazil.
What time will the 2027-02-06 annular solar eclipse reach greatest eclipse?
Greatest eclipse occurs at 16:00 UTC on 2027-02-06 (Coordinated Universal Time). To convert to local time for your city, the conversion uses the IANA timezone for that locale — the WorldClockTools eclipse-calendar page surfaces the conversion automatically for any of the listed cities.
How long will annularity last during the 2027-02-06 eclipse?
Maximum annularity on the central line lasts 7m 51s. Observers off the central line see shorter durations; NASA's interactive map gives the local figure for any coordinates.
When is the next solar eclipse after the 2027-02-06 annular solar eclipse?
The next solar eclipse after 2027-02-06 is the total solar eclipse on 2027-08-02 (10:07 UTC). It will be visible from spain, morocco, algeria, libya, egypt, sudan, saudi arabia, yemen, somalia.
Do I need eclipse glasses to watch the 2027-02-06 annular solar eclipse?
Yes — for any solar eclipse (partial, annular, or total), looking directly at the Sun without ISO 12312-2 certified solar viewing glasses or an equivalent solar filter is unsafe and can cause permanent retinal damage. During totality only — the brief window when the Moon completely covers the Sun on the central line — it is safe to look at the eclipsed Sun with the naked eye, but glasses MUST go back on the moment Baily's beads reappear.
What is the Saros series for the 2027-02-06 annular solar eclipse?
Annular Solar Eclipse of 2027-02-06 is member 55 of 70 of NASA Saros series 131. Each Saros series produces an eclipse every 18 years 11 days, with successive members shifted roughly 120 degrees west in longitude. Saros series typically span 12 to 15 centuries and contain 70 to 80 eclipses each.

Eclipse data depth

What the annular solar eclipse entry signals

A compact read of the NASA catalog row: Saros context, magnitude / obscuration math, path geometry, and the city / country cross-references that pair annular solar eclipse with WorldClockTools local-clock pages.

Saros series context

Annular Solar Eclipse 2027-02-06 is member 55 of 70 of NASA Saros series 131. Each Saros member repeats roughly every 18 years 11 days, shifted ~120 degrees west, so adjacent members in the same series land on different continents.

Magnitude and obscuration

Magnitude is 0.928 (NASA convention: fraction of Sun diameter eclipsed), and the Sun's area is obscured by 86.1%. Magnitude is the diameter ratio; obscuration is the area ratio — both come from the same NASA prediction.

Duration on the central line

Maximum totality / annularity duration is 7m 51s on the central line. Off-central observers see shorter duration; precise local duration is on NASA's interactive map.

Path and visibility footprint

The central path crosses argentina and chile. Partial phases reach a wider 4-country zone in the current catalog cut.

City cross-references

Cross-referenced cities in the WorldClockTools catalog that fall in the path or partial band: Buenos Aires, Santiago, and Punta Arenas. Each city has its own clock page; pairing the eclipse time with the local clock gives the immediate local-time answer.

Gamma and geometry

Gamma is -0.2952 — the lateral distance of the Moon's shadow axis from Earth's center at greatest eclipse, in Earth-radii. |gamma| < 1.0 places the shadow axis on the Earth disc — a central eclipse with a true path of totality or annularity.

What is notable

One of the longest annular eclipses of the 2020s at 7 minutes 51 seconds maximum annularity. Saros 131 produces these long annulars near aphelion.
