A total lunar eclipse on March 3, 2026, captivated skywatchers across the Americas, Asia, and Australia, but a particularly striking feature caught the attention of photographers: a rare, vibrant blue line visible along the edge of the moon during totality. The phenomenon, caused by the scattering of sunlight through Earth’s atmosphere, offered a unique visual spectacle during the “blood moon” event.
The March 2026 lunar eclipse was notable as the last total lunar eclipse until the New Year’s Blood Moon Eclipse on December 31, 2028–January 1, 2029. During a total lunar eclipse, the Earth passes between the Sun and Moon, casting a shadow on the lunar surface. While often appearing reddish due to the refraction of sunlight, specific atmospheric conditions can create other colors, including the unusual blue hue observed this week. The eclipse was visible in cities including Los Angeles, New York, Manila, and Sydney, offering a wide range of locations to witness the event.
What Caused the Blue Line?
The blue line, as captured in photographs, is a result of Rayleigh scattering, the same effect that makes our sky blue. When sunlight passes through Earth’s atmosphere, shorter wavelengths of light (blue and violet) are scattered more effectively than longer wavelengths (red and orange). During a total lunar eclipse, some sunlight still reaches the moon by bending through Earth’s atmosphere. If the atmosphere is particularly clear and free of dust or clouds, more blue light can be refracted around the Earth and onto the lunar surface, creating the visible blue fringe.
According to Time and Date, the period of totality – when the moon was fully within Earth’s umbral shadow – lasted from approximately 11:04 to 12:03 UTC on March 3. The maximum point of the eclipse occurred at 11:33 UTC. The visibility varied depending on location, with the eclipse occurring before sunrise in the Americas and during the evening in East Asia and Australia.
Global Visibility and Live Coverage
The total lunar eclipse was visible across a broad swath of the globe, including regions in Europe, Asia, Australia, North America, South America, the Pacific, Atlantic, and Indian Oceans, as well as the Arctic and Antarctica. Space.com provided live updates throughout the event, featuring photos and observations from around the world. The eclipse was particularly well-observed in North America, with many photographers capturing the rare blue line.
The eclipse also drew attention in Asia, with reports from Pakistan noting its visibility. Xinhua News Agency shared a series of photos documenting the event, showcasing the blood moon’s appearance from various locations. In Tucson, Arizona, the event was described as a “solar system ballet” resulting in an early-morning blood moon, according to AZPM News.
Looking Ahead
The March 3, 2026, total lunar eclipse provided a stunning celestial display and a unique opportunity for photographers to capture a rare atmospheric phenomenon. With the next total lunar eclipse not expected until late 2028, this event served as a reminder of the beauty and wonder of our solar system. Future lunar events will continue to be closely watched by astronomers and enthusiasts alike, offering further insights into the dynamics of Earth, the Moon, and the Sun.
