Understanding the “Double Sunrise” Phenomenon
A partial solar eclipse happens when the Moon passes between the Earth and the Sun, partially obscuring the Sun’s light. In certain locations, particularly along the northeastern coast of North America, this alignment creates a visual effect where the Sun appears to rise, then momentarily disappear behind the Moon, and rise again—a phenomenon often referred to as the “double sunrise” or “devil’s horns.” This occurs because the Moon’s shadow causes the Sun’s cusps to separate, forming two distinct points above the horizon.
Optimal Viewing Locations
The “double sunrise” effect will be most prominent in the following areas:
- Northeastern United States: Regions such as eastern Maine, New Hampshire, and Massachusetts will experience significant eclipse coverage during sunrise. citeturn0search0

Viewing Times
The timing of the eclipse varies by location:
- United States (Eastern Time):
- Start: Approximately 6:13 a.m. EDT
- Maximum Eclipse: Around 6:45 a.m. EDT
- End: Approximately 7:17 a.m. EDT
- Canada (Eastern Time):
- Start: Around 6:15 a.m. EDT
- Maximum Eclipse: Near 6:50 a.m. EDT
- End: Approximately 7:20 a.m. EDT
It’s important to arrive at your chosen viewing location early to set up and ensure an unobstructed view of the horizon.
Safety Precautions for Viewing
Observing a solar eclipse requires strict eye safety measures to prevent permanent eye damage:
- Eclipse Glasses: Use only certified eclipse glasses that meet the ISO 12312-2 safety standard. Regular sunglasses, even dark ones, are not safe for direct solar viewing.
- Pinhole Projectors: Create a simple viewer by projecting the Sun’s image through a small hole onto a flat surface, allowing you to observe the eclipse indirectly.
- Solar Filters for Optics: If using telescopes, binoculars, or cameras, ensure they are equipped with proper solar filters. Never look through optical devices without solar filters specifically designed for eclipse viewing.
Always supervise children and ensure they adhere to safety guidelines.
Additional Viewing Tips
- Weather Considerations: Check local weather forecasts for clear skies on the morning of the eclipse. Cloud cover can obstruct visibility.
- Photography: If capturing the event, use appropriate solar filters for your equipment. Avoid looking directly through cameras or telescopes without filters.
- Stay Informed: For real-time updates and detailed maps, refer to reputable sources such as NASA’s eclipse page. citeturn0search5
Conclusion
The partial solar eclipse on March 29, 2025, offers a rare opportunity to experience the “double sunrise” effect in select regions of North America. By choosing optimal viewing locations, adhering to safety guidelines, and being mindful of timing, observers can witness this celestial event in all its glory. Remember, protecting your eyes is paramount—never look directly at the Sun without proper eye protection.
