'Devil's horns' will appear in upcoming solar eclipse—What are they
What's the story
On March 29, 2025, parts of the northeastern United States and eastern Canada will witness a partial solar eclipse.
The event gives residents of these regions a rare chance to see "solar horns," an optical phenomenon.
Solar horns, also known as Devil's horns, refer to the crescent-shaped parts of the Sun that remain visible during a partial eclipse.
The shape of these "horns" can vary depending on the observer's location and the degree of the eclipse.
Viewing locations
Best spots to catch 'solar horns'
The "solar horns" will be visible from southeastern Quebec and southwest New Brunswick in Canada, and northern Maine in the US
Specifically, the phenomenon will occur between the St. Lawrence River estuary and Bay of Fundy.
An unobstructed view of the eastern horizon is essential for optimal viewing, making coastal areas and elevated terrain ideal spots.
Additional locations
Other places to see an eclipsed sunrise
On Saturday, the Sun will rise while eclipsed, with the Moon's silhouette creating the spectacle of "solar horns" or a "double sunrise."
While "solar horns" can only be spotted in Quebec, New Brunswick, and Maine (if skies are clear), an eclipsed crescent sunrise will be visible from several other locations.
Areas with an ocean horizon are best suited for viewing. A slightly eclipsed sunrise will also be visible from New York, Pennsylvania, Maryland, Washington D.C., and Virginia.
Eye protection
Safety measures for viewing the solar eclipse
It is important to note that gazing at the Sun without proper eye protection can lead to severe damage.
Normal sunglasses don't offer sufficient protection.
The only safe way to gaze directly at the Sun during an eclipse is through specially designed equipment such as solar eclipse glasses for direct viewing and solar filters for telescopes and binoculars.
