The Rare Celestial Alignment: When the Sun and ‘Blood Moon’ Meet
On March 3, 2026, a remarkable astronomical event will unfold: a total lunar eclipse coinciding with sunrise. This unusual pairing offers a rare opportunity to witness what’s known as a selenelion – the simultaneous appearance of the sun and a fully eclipsed moon in the sky. While lunar eclipses themselves aren’t uncommon, seeing them alongside the rising sun is a truly special occurrence, traditionally considered impossible due to the geometry of the alignment.
Why is a Simultaneous Sunrise and Lunar Eclipse So Rare?
Typically, a lunar eclipse happens when the Earth passes directly between the sun and the moon, casting a shadow on the lunar surface. This means the sun, Earth, and moon are in a straight line. Logically, if the sun is above the horizon, the moon should be below it, and vice versa. However, atmospheric refraction – the bending of light as it passes through the Earth’s atmosphere – makes this seemingly impossible sight a reality.
Atmospheric refraction causes astronomical objects to appear higher in the sky than they actually are. This effect is the same reason we see the sun for a few extra minutes at sunrise and sunset. It bends the light, allowing us to see the sun even when it’s technically below the horizon. The same principle applies to the eclipsed moon, potentially bringing it into view alongside the rising sun.
Where Will the Selenelion Be Visible?
The best views of the total phase of the eclipse will be from locations near and around the Pacific Rim. For North America, those in the Eastern Time Zone will see the moon set during dawn, while locations further west may catch the moon emerging from the Earth’s shadow as it sets. Hawaiians are particularly well-positioned, with the moon appearing almost overhead during totality. Central Asia and western Australia will see the moon rise as it emerges from the shadow, and eastern Australia, Papua Recent Guinea, Japan, and eastern Siberia will have convenient evening views.
What to Expect During the Eclipse
Totality will begin at 3:03 a.m. PST and last for 59 minutes. The moon will pass through the southern part of Earth’s shadow. The window for observing the selenelion will be brief, lasting roughly 1-3 minutes, depending on your location. The moon may appear as a dim, eerily illuminated object on the western horizon.
The Last Eclipse Until 2029
This eclipse is particularly noteworthy as it will be the last total lunar eclipse visible until 2029. This extended period without a total lunar eclipse makes this event even more significant for skywatchers and astronomy enthusiasts.
FAQ
What is a selenelion? A selenelion occurs when the sun and a fully eclipsed moon are visible in the sky at the same time, made possible by atmospheric refraction.
Will I be able to see the eclipse with the naked eye? Yes, a lunar eclipse is visible with the naked eye. No special equipment is needed.
What causes the moon to turn red during a lunar eclipse? The moon appears red during a total lunar eclipse because sunlight is scattered and refracted through Earth’s atmosphere, filtering out most colors except red.
Where can I find more information about the eclipse? You can stay up to date with the latest information in a lunar eclipse live updates blog.
