A rare partial solar eclipse will rise over parts of North America and Europe on Saturday 29 March 2025, offering early risers a dramatic display – including a 'double sunrise'.
“From wherever you see the eclipse, it will be a wonderful sight,” Prof Darren Baskill, astronomy lecturer at the University of Sussex, told BBC Science Focus. “It reminds us of the mechanics and natural rhythms of our solar system.”
The eclipse begins globally at 4:50am EDT (8:50am GMT) and ends by 8:43am EDT (12:43pm GMT), with maximum eclipse at 6:47am EDT (10:47am GMT).
It will be visible across 14 US states – Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, Vermont, Virginia and West Virginia – as well as Washington DC and parts of eastern Canada.
For viewers in the US, the event will take place from 6:13am through to 7:17am EDT.
Maine will have some of the best views, with up to 85 per cent of the Sun obscured in areas like Presque Isle. In Maine too, along with New Brunswick and Quebec, the eclipse will already be in progress at sunrise to a large enough extent to give rise to the rare 'double sunrise' effect.
This occurs when, as the crescent Sun rises, the two pointed tips – sometimes called “devil’s horns” – appear to rise separately, creating the brief illusion of two suns emerging from the horizon.

“It’ll look quite weird. Instead of seeing a semicircle coming up as you would normally, there’ll be a bite out of it,” said Prof Peter Gallagher, solar physicist at DIAS Dunsink Observatory, speaking to BBC Science Focus. “That’ll be really cool looking, for sure.”
To view the eclipse safely, use certified eclipse glasses or solar filters on cameras and telescopes. Do not look at the Sun without protection.
Gallagher also suggested looking at the ground under trees during the eclipse: “The gaps between the branches and leaves essentially form lots of pinhole cameras, projecting tiny crescent shapes onto the ground.
“It’s one of the most beautiful things about partial solar eclipses, I think; seeing all these tiny eclipses all over the place.”
Can’t get outside? The Royal Observatory Greenwich will be streaming the event live from 10:00am GMT.
