March 2025 Partial Solar Eclipse: Where and How to Watch Safely

In-Depth Analysis

### Eclipse Path and Timing The visibility and timing of the March 29, 2025, partial solar eclipse depend heavily on your location.

For viewers in the **Northeastern United States and Eastern Canada**, the spectacle begins *before or exactly at sunrise*. For instance, in Syracuse, NY, sunrise is around 6:50 AM local time, with the maximum (though small, ~2-10% coverage) occurring shortly after, ending by about 7:09 AM. Cities like Boston (max ~43% at 6:38 AM) and Portland, Maine (max ~64% at 6:30 AM) will see greater coverage, also beginning around sunrise. Further north, Halifax, Canada, will witness an impressive 83% coverage peaking at 7:17 AM local time.

Across the Atlantic in **Europe and Northwestern Africa**, the eclipse happens later in the morning. Londoners can expect maximum coverage (~31%) around 11:03 AM local time. Paris will see ~24% coverage around 12:01 PM, Madrid ~21% around 11:40 AM, and Berlin ~15% around 12:19 PM.

### Safe Viewing is Non-Negotiable Since the Sun will never be fully blocked, **safe viewing techniques are mandatory throughout the entire event**.

• **Eclipse Glasses/Viewers:** Use only **ISO 12312-2 compliant** solar viewers. Regular sunglasses are **not safe**. Inspect your glasses for scratches or damage before use.
• **Optical Devices:** **Do NOT** look through cameras, binoculars, or telescopes *while wearing eclipse glasses*. The focused sunlight will burn through the filter and cause severe eye injury. These devices require their own specialized solar filters attached securely to the **front end**.
• **Indirect Viewing:** If you don't have safe viewers, use a pinhole projector. Punch a small hole in a card, stand with your back to the Sun, and project the Sun's image onto a surface (like the ground or another card). You can also look for natural pinholes, like the spaces between tree leaves, projecting crescent shapes onto the ground.

### What Else to Look For? While safely observing the eclipse, you might also be able to spot sunspots – dark, cooler areas on the Sun's surface. Use your eclipse glasses or filtered optics to look for them!
