On March 29, 2025, a captivating partial solar eclipse will grace the skies over North America and parts of Europe, featuring the extraordinary phenomenon known as the “devil’s horns.” Ideal viewing spots for this awe-inspiring event will be primarily in coastal regions and high elevations, particularly throughout the northeastern United States and the southeastern Canadian provinces.

As the new moon begins to obscure the sun during its ascent on that Saturday morning, observers will be treated to a breathtaking celestial display. Although we expect a thrilling partial solar eclipse, the highlight will undoubtedly be the appearance of the so-called solar horns. This stunning visual effect creates an image where the sun appears as two glowing points along the horizon instead of its usual round shape.

Understanding the Partial Solar Eclipse

In contrast to a total solar eclipse, this event will never completely obscure the sun, meaning safety will be paramount. Eclipse glasses, or solar filters, will be essential for viewing at all times during the event. The eclipse is slated to commence in the United States between 6:13 and 7:17 a.m. EDT and will continue into Canada from 6:56 a.m. NDT to 8:20 a.m. EDT, with western Europe experiencing the phenomenon a bit later in the morning.

Thirteen northeastern states in the U.S., including Maine, New York, and Pennsylvania, will witness the partial eclipse, with coastal areas providing the most dramatic views due to unobstructed perspectives of the eastern horizon.

The Fascinating ‘Devil Horns’ Phenomenon

The “devil’s horns,” or solar horns effect, occurs when the moon obscures the sun's center while leaving the edges illuminated, creating an eerie yet captivating sight. The phenomenon is further enhanced by atmospheric distortions near the horizon, which may stretch or compress the appearance of the horns, resulting in an experience that is both surreal and mesmerizing for viewers.

Where to Catch the ‘Solar Horns’ Show

For optimal viewing of the solar horns, locations in southeastern Quebec and southwest New Brunswick, Canada, as well as northern Maine in the U.S., will serve as prime spots. Reports indicate that areas between the St. Lawrence River estuary and the Bay of Fundy will be particularly favorable for experiencing this spectacle. Coastal terrains and elevated locations with unobstructed views will be essential to witness the full effect.

Eager eclipse watchers can utilize helpful tools such as Xavier Jubier’s interactive Google Map designed for eclipse viewing, The Photographer’s Ephemeris, and Timeanddate.com’s eclipse mapping resources to find the perfect vantage points. A compass may also come in handy to ensure proper alignment with the sun’s rising arc.

Don’t miss this once-in-a-lifetime opportunity to witness the awe-inspiring devil’s horns effect. Mark your calendars for March 29, 2025, and prepare for an unforgettable encounter with the cosmos!
