Where totality lasts longest
The Moon's shadow first touches Earth at sunrise over the Atlantic, crosses the Strait of Gibraltar, where southern Spain, Gibraltar and northern Morocco see totality, and then runs along the coast of North Africa through Algeria, Tunisia and Libya. It crosses Egypt, where totality lasts longest, near Luxor, then the Red Sea, western Saudi Arabia including Jeddah and Mecca, Yemen and the northern tip of Somalia, before leaving Earth at sunset over the Indian Ocean.

Why this eclipse is so long
How long totality lasts depends on how much bigger the Moon looks than the Sun, and how fast its shadow sweeps across the ground. On August 2, 2027, several things work in its favor:
The Moon passes its closest point to Earth only hours earlier, so it looks unusually large.
Earth reached its farthest point from the Sun in early July, so the Sun looks slightly smaller than average.
Over Egypt the Sun is almost straight overhead, and close to the equator the ground itself moves eastward fastest, partly keeping pace with the shadow. Both slow the shadow's speed across the ground.
A longer total eclipse over land won't happen until June 3, 2114.
Watching safely
Never look at the Sun directly, even when most of it is covered: a thin crescent can still burn your retina, and you won't feel it happening. Ordinary sunglasses are not enough.
Use eclipse glasses or handheld viewers that meet the ISO 12312-2 standard, from a reputable supplier, and check them for scratches first.
Cameras, binoculars and telescopes need a proper solar filter over the front. Never use them through eclipse glasses.
A pinhole projector, even the gaps between your fingers or leaves on a tree, lets you watch the crescent Sun's image safely.
Only during totality, when the Moon completely covers the Sun, is it safe to look with your bare eyes. Put your glasses back on as soon as the Sun starts to reappear.

How this is calculated
The path, local times and the calculator use the Astronomy Engine library. We checked the path against NASA's published path table: our central line and limits are within about 3 km of NASA's, and points 4 km inside NASA's limits see totality while points 4 km outside don't. Our durations of totality run about 2-4 seconds longer than NASA's, because of a small difference in the assumed size of the Moon; the longest duration shown above is NASA's.
