A Historic Astrophotography Triumph

In a stunning feat of amateur astronomy, a trio of dedicated eclipse hunters has accomplished something once thought impossible: the first documented capture of the solar corona—an incredible phenomenon typically only seen during the fleeting moments of totality in a solar eclipse—during a partial eclipse.

Unveiling the Solar Corona

These remarkable images were snapped on March 29, 2025, in Quebec, Canada, revealing the sun’s outer atmosphere at an impressive 87% coverage. "The corona is often photographed during total or annular eclipses, but capturing it during a partial eclipse was unheard of," exclaimed Mike Kentrianakis, an eclipse chaser and noted astrophotographer.

Facing the Elements: A True Adventure

Braving frigid temperatures of just 14°F (-10°C), Kentrianakis and fellow shutterbug Kevin Wood set up along the bleak shores of Les Escoumins, Quebec. They anticipated a breathtaking view of the sun slicing through the horizon, creating what Kentrianakis dubbed "solar headlights"—an effect likened to a glorious double sunrise. To their astonishment, these photos also revealed the elusive solar corona—the result of a remarkable alignment of conditions.

A Photographic Wonder Unfolds

Not merely content with capturing this unprecedented view, the duo meticulously utilized advanced astronomy apps to gauge not just their timing but to seize the moment as the sun eclipsed the moon. "I didn't know what I would end up with," Kentrianakis reflected. What he got was a sensational blend of light that not only visually stunned but also broke new ground in solar studies.

The Science Behind the Discovery

Until now, it was believed that the solar corona—a million times dimmer than the sun's surface—could only be witnessed during total eclipses due to its low luminosity. Solar physicist Matt Penn remarked, "This could revolutionize future studies of the corona!" It was a perfect storm of atmospheric clarity and eclipse depth that allowed this exceptional visibility—conditions that may be rare but manageable with the right gear.

Revolutionizing Future Eclipses

The implications of this achievement extend beyond a mere photograph. As Penn notes, this newfound method could pave the way for future observations and inspire amateur astronomers worldwide to pursue the beauty hidden in more commonplace eclipses. Kentrianakis’s endeavor shines a light on the untapped potential of partial eclipses, inviting curiosity and excitement.

Look Toward the Skies! Upcoming Eclipses Await

Eager eclipse enthusiasts can mark their calendars; another opportunity to witness a partially eclipsed sunrise will grace the skies on September 21, 2025, though it will be observable only from Antarctica. Following that, January 14, 2029, offers a chance for those in western Canada.

Kentrianakis encapsulates the thrill of this adventure: "Most people dismiss partial eclipses, but my experience shows there's so much more to discover!" This groundbreaking revelation serves as a testament to the wonders of amateur astronomy and the extraordinary phenomenon of the solar corona.
