Full Moon Captured in Rare 'Lunar Rainbow' Phenomenon Over Pacific Ocean
LOS ANGELES, CA – A stunning atmospheric event known as a "full moon rainbow," or lunar rainbow, was observed and photographed on Wednesday night across multiple locations along the Pacific Coast.
WHAT: A lunar rainbow, also known as a moonbow, is an optical phenomenon caused by the refraction of moonlight through water droplets in the atmosphere. Unlike a solar rainbow, which is common during the day, a full moon rainbow is exceedingly rare due to the specific conditions required, including a near-full moon, clear skies, and abundant moisture from ocean spray or rain.
WHO: The event was documented by professional meteorologists and amateur astronomers in California, Oregon, and Washington. The National Weather Service confirmed the sightings, with multiple images spreading rapidly on social media platforms.
WHEN: The phenomenon was observed at approximately 11:45 PM Pacific Time on Wednesday, coinciding with the peak illumination of the full moon.
WHERE: Primary sightings were reported along the Pacific Coast, particularly near the Golden Gate Bridge in San Francisco, the Oregon Dunes National Recreation Area, and the Olympic National Park in Washington.
WHY: Scientists attribute the occurrence to a combination of seasonal weather patterns, including residual moisture from recent storms and the moon's position low on the horizon, which maximizes the refraction of its light.
HOW: The full moon rainbow appears as a pale, white arc to the naked eye, but long-exposure photography reveals subtle bands of color, including red, blue, and green. This is because moonlight, while significantly dimmer than sunlight, carries sufficient spectral energy to produce a visible spectrum under optimal conditions.
Authorities have encouraged residents and tourists to look for potential reoccurrences over the next two nights as the full moon remains bright and atmospheric conditions persist.
