Partial Solar Eclipse Set To Dazzle Skywatchers On March 29

Millions prepare for a celestial show as the Moon partially obscures the Sun across North America and Europe.

Skywatchers across the Northern Hemisphere are gearing up for a spectacular partial solar eclipse set to unfold on Saturday, March 29, 2025. This celestial event, which will see the Moon partially obscure the Sun, is expected to capture the attention of millions, especially those in northeastern Canada and parts of the United States.

The eclipse will begin at 4:50 a.m. Eastern Time (ET) and last nearly four hours, peaking around 6:40 a.m. in Montreal, where 47 percent of the Sun will be blocked, weather permitting. In Burlington, Vermont, observers can expect about 45 percent coverage at the peak time of 6:41 a.m., just a few minutes after sunrise at 6:38 a.m.

However, not everyone will have the best view. Environment Canada has issued a special weather statement warning of snow and freezing rain across Southern Quebec, which could hinder visibility. In the U.S., cloudy skies may obstruct views in Boston and parts of eastern Canada, while the mid-Atlantic region, including New York and New Jersey, may offer clearer conditions.

According to NASA, the central part of the Moon's shadow will miss Earth during this event, which means there will be no total solar eclipse visible anywhere on the planet. Instead, observers will see a crescent shape as the Moon partially covers the Sun. NASA emphasized the importance of using proper eye protection or indirect viewing methods, such as a pinhole projector, to safely observe the eclipse.

Experts recommend several tips for capturing stunning images of the eclipse. First, it’s crucial to use a solar filter above your smartphone camera to prevent damage to both your eyes and the camera lens. Additionally, taking photos of your surroundings can yield beautiful landscape shots, especially where light filters through leaves. It’s best to use the primary camera rather than an ultrawide lens, as the latter will make the Sun appear smaller. If available, a telephoto lens can enhance the image quality.

For those unable to view the eclipse in person, live streams will be available from various observatories, including the Royal Greenwich Observatory in England, which will start streaming at 6 a.m. local time.

In Europe, some regions may experience better visibility than others. Paris and Madrid are expected to have clear skies, while northern Europe and England may face cloud cover. In Africa, Casablanca is predicted to offer ideal viewing conditions under sunny skies.

The partial solar eclipse is not just an astronomical event; it also serves as a reminder of the intricate movements of celestial bodies. As the Moon passes between the Earth and the Sun, it creates a fascinating visual spectacle that captivates both casual observers and seasoned astronomers alike.

Safety is paramount during such events. Jake Foster from the Royal Observatory explained, "If people want to directly view it, to actually look up at the sun, they are going to need a pair of solar eclipse glasses or a solar viewer. Those make use of a special filter that blocks out 99.9999% of the sun’s light, which makes it safe for us to view." For those without eclipse glasses, simple alternatives such as using a colander or creating a pinhole projector can provide safe viewing methods.

As the eclipse approaches, skywatchers are reminded of the next major solar event: a total solar eclipse expected in August 2026, which will be visible across much of Europe, including parts of Spain and Portugal.

With over 800 million people expected to witness the partial solar eclipse on March 29, 2025, this event promises to be a memorable experience for astronomy enthusiasts and casual viewers alike. Whether through the lens of a camera or simply enjoying the moment with friends and family, the partial solar eclipse will undoubtedly leave a lasting impression.

As the date draws nearer, preparations are underway across various regions. Observatories and astronomy centers are gearing up to provide safe viewing opportunities and educational resources about this astronomical phenomenon. For those looking to capture the moment, fine-tuning camera settings such as focus, shutter speed, and ISO can result in stunning images of the eclipse.

In summary, the March 29, 2025, partial solar eclipse is an exciting opportunity for skywatchers across the Northern Hemisphere. With the right equipment and clear skies, viewers can witness a breathtaking celestial display. Don’t forget to mark your calendars, prepare your eclipse glasses, and enjoy this extraordinary event!
