Millions of people across the Northern Hemisphere will have the chance to witness a solar eclipse on August 12, with a narrow path of totality crossing remote Arctic regions, Iceland and northern Spain while a much broader partial eclipse stretches across Europe, parts of North Africa and northeastern North America.

The total solar eclipse occurs when the Moon completely covers the Sun's disk, briefly darkening the sky and revealing the solar corona. Greatest eclipse takes place over the North Atlantic near Iceland, where totality is expected to last up to 2 minutes and 18 seconds. The path of totality is relatively narrow, roughly 180 to 190 miles wide at points, and will sweep from the Arctic across eastern Greenland, western and northern Iceland, then southeast across the Atlantic to make landfall in northern Spain before ending near the Balearic Islands around sunset.

Approximately 15 million people live within or near the path of totality. Nearly one billion people could potentially see at least a partial eclipse, according to visibility estimates.

In Iceland, Reykjavik sits near or within the path. Partial phases are expected to begin in the late afternoon, with totality around 5:48 p.m. to 5:49 p.m. local time lasting roughly one minute, followed by the end of partial phases near 6:47 p.m. Western coastal areas of Iceland may........
