The 2 August 2027 eclipse, town by town

How long totality lasts, and at what time on the local clock, for 14 towns along the path. Every figure is computed for that town's own coordinates with the same engine, so they are directly comparable.

The headline: Sohag, Egypt gets 6 min 26 sec, the longest on this list. The longest totality available anywhere on this eclipse is 6 min 27 sec, at latitude 27.37 north, longitude 30.16 east, in the Western Desert about 100 km west of the Nile; every town below is within a few seconds of that or well short of it, and nothing on land beats it. The main page for this eclipse has the global circumstances and the shape of the path.

Inside the path of totality

Sorted by how long the Sun is completely covered. Local time is the town's own clock time at maximum eclipse.

Close, but outside the path

These towns see a deep partial eclipse and no totality at all. The difference is not a matter of degree: without totality there is no corona, the sky does not go dark, and filters never come off. If you are travelling for this eclipse, being in one of these towns on the day is the one mistake worth real effort to avoid.

Anywhere else

This list is a sample of the path, not all of it. For any other location, including a specific hotel or a spot out on the center line, the Eclipse Explorer computes contact times and obscuration for coordinates you give it. Place names and coordinates here come from GeoNames (geonames.org), CC BY 4.0.

How these were computed

Contact times come from the open-source Astronomy Engine, the same one behind every other page on this site and the public API, run at each town's GeoNames coordinates at sea level. Durations are quoted to the second because the computation is deterministic, not because a second is meaningful to a person standing there: move a few kilometres toward the center line and it changes. The methodology page covers the conventions, and the numbers themselves are public-domain facts you may reuse freely.

Two figures get confused wherever this eclipse is written about, and they are not the same thing. Greatest eclipse is the moment the axis of the Moon's shadow passes closest to Earth's center; greatest duration is where totality lasts longest. They fall at different places, and the duration quoted at greatest eclipse is a few seconds short of the real maximum. The 6 min 27 sec above is greatest duration, found by scanning the path with the same engine. Where a source quotes about 6 min 23 sec for this eclipse, it is almost certainly quoting greatest eclipse instead.

One more convention worth stating: these are mean-limb figures. The Moon's edge is mountainous, and a limb-corrected calculation shifts the second and third contact instants by a second or two either way depending on which valley the last sliver of Sun drains through. That correction is beyond what this page computes, and it is smaller than the difference a short drive makes.
