August 12, 2026 Partial Solar Eclipse: When and Where to Watch Across the U.S. and Canada

On the morning of August 12, 2026, a partial solar eclipse will glide across the North American sky. While it won’t reach the dramatic totality of the 2024 event, millions from the United States and Canada will still see the Moon carve a noticeable bite out of the Sun. The eclipse will occur during daylight hours, offering a convenient window for casual observers and educators alike. Because the Sun’s light will be only partially blocked, safe viewing practices are essential.

What happened

The Moon will pass between Earth and the Sun on August 12, casting a shadow that only partially covers the solar disk. In the United States, the eclipse will be visible in 20 states, with the earliest start around 7:34 a.m. AKDT and the latest end near 2:52 p.m. EDT. Northeastern states will experience the deepest coverage, with the Moon obscuring roughly two‑thirds of the Sun at maximum.

In Canada, every province will see some degree of the eclipse. The event will begin as early as 8:38 a.m. MST and conclude around 4:38 p.m. NDT, with eastern provinces enjoying the most substantial bite. The partial phase lasts about 55 minutes before and after the moment of greatest coverage at each location.

Why it matters

A partial eclipse of this scale provides a rare, low‑cost opportunity for public outreach and hands‑on science education. Schools, planetariums, and amateur astronomers can use the event to teach about celestial mechanics, solar physics, and the importance of eye safety. Although it lacks the awe of totality, the widespread visibility means a larger portion of the population can experience a real astronomical phenomenon, potentially sparking lifelong interest in space.

How to think about it

First, check the local start, maximum, and end times for your city using a reliable eclipse calculator. Second, obtain certified solar‑eclipse glasses that meet the ISO 12312‑2 standard; never substitute regular sunglasses. Third, choose a viewing spot with an unobstructed horizon and minimal light pollution. If you plan to photograph the event, use a solar filter on your camera lens and practice proper exposure settings ahead of time. Finally, consider pairing the viewing with a brief talk or activity about the Sun‑Moon‑Earth geometry to deepen the experience.
