Total Solar Eclipse
For up to 2 minutes and 18 seconds, day becomes night along a path from the Arctic across Greenland and Iceland to northern Spain. Iceland's first totality since 1954. Mainland Spain's first since 1905.

The Path
The shadow runs east to west — unusual for an eclipse — beginning at sunrise over northern Siberia, skimming past the North Pole, crossing Greenland and Iceland, then sweeping down the Atlantic to make landfall in northern Spain about an hour before local sunset. Everyone inside the dark band gets totality; the rings around it show how deep a partial bite the rest of Europe, West Africa, and northeastern North America will see.
From Where You Stand
Eclipses are local events. The same moment is a black sun over Reykjavík, a deep bite out of the evening sun in Paris, and an ordinary Wednesday in California. This is what August 12 looks like from your spot — computed in your browser, nothing sent anywhere.

The Day, As It Happens
Afternoon UTC
First contact over the Arctic — the moon takes its first bite out of the sun at local sunrise in northern Siberia, and the partial eclipse begins spreading across the top of the world.
~17:15 UTC
The full shadow touches down and begins its run: over the pole's shoulder, then down across Greenland's ice sheet.
~17:48 UTC
Iceland goes dark. Reykjavík sits inside the band for about a minute of totality; the shadow's center passes just offshore, where darkness lasts the full 2m 18s.
17:47:06 UTC
Greatest eclipse — magnitude 1.039, 40 mi (65 km) west of Iceland's coast. Up to 2m 18s of totality.
~18:27 UTC
Landfall in Spain. The shadow crosses the north coast with the sun hanging low in the west, sweeps southeast, and exits past the Balearic Islands at dusk.
Two weeks later
On the night of August 27–28 the full moon slides through Earth's shadow — a partial lunar eclipse for the Americas, Europe, and Africa. The Moon room computes your local circumstances for that one too.
The Cloud Question
Decades of August satellite records say the smart money is on Spain's Ebro Valley; Iceland is a coin flip with a spectacular upside. These are historical August clear-sky odds along the path — in the final days this panel gives way to the real forecast.

Eclipse Day: This Page Goes Live
On August 12 this page stops counting down and starts showing — the sun as SDO sees it, curated webcasts from inside the path, and the observatory's signature view: the moon's shadow itself, photographed from orbit as it crosses the Atlantic.
The sun right now. SDO's 171 Å view, refreshed through the eclipse.
The shadow from space. GOES-East full disk — watch for the dark
smudge sliding across the North Atlantic. That's the umbra.
Live from the path
Curated webcast links appear here on the day — streams from Iceland and Spain, plus timeanddate's broadcast.
Webcasts. For everyone outside the path — which is most of us.
The live panels wake up on eclipse day. Afterward, this page becomes the permanent record — the shadow crossing as a replay, and the local-circumstances tool stays live for August 2, 2027, when the moon's shadow returns to cross Egypt.
Why This One Matters
Totality is the only time human eyes can see the corona — the sun's outer atmosphere, a million-degree halo shaped by the same magnetic field lines the Space Weather room tracks every day. This eclipse arrives near solar maximum, so expect a full, spiky crown rather than the trim streamers of a quiet sun. And it's a rare visit: the moon's shadow hasn't touched Iceland in 72 years, and mainland Spain has waited 121. If you're anywhere near the path on August 12 — go. Cloud odds and all, nothing on this site compares to standing inside the shadow.
