Where the annular path goes
The central annular path crosses southern Chile and Argentina, then continues across the South Atlantic. A much wider partial eclipse reaches other parts of South America, Antarctica and portions of western and southern Africa.
Annularity is visible only from inside the narrow antumbral path. Locations outside it see a partial eclipse, even when most of the Sun is covered.
Key global circumstances
| Measure | Value | Planning meaning |
|---|---|---|
| Greatest eclipse | About 16:00 UTC | Convert to local time for the exact site |
| Maximum central duration | About 7m 51s | Local duration varies along the path |
| Path width | About 282 km | Confirm the observing point is inside both path limits |
| Eclipse magnitude | 0.928 | A bright ring of sunlight remains at maximum |
How to plan for annularity
- Use an official path map and exact coordinates rather than a country label.
- Check the Sun's altitude and azimuth for the selected site.
- Compare climate first, then use current forecasts close to the event.
- Choose at least one backup site connected by practical roads.
- Keep certified solar protection on throughout the entire eclipse.
Why eye protection never comes off
An annular eclipse is not total. The Moon appears too small to cover the complete solar photosphere, so a brilliant ring remains visible throughout the central phase.
Certified eclipse glasses are required for direct viewing. Cameras, binoculars and telescopes need a purpose-built solar filter securely mounted over the front aperture.
