"Moonbow this year was phenomenal with epic snowpack in the Sierra Nevada!" Manievannan wrote on Instagram. "This is a combo of real-time video capture along with Timelapse shots to capture the trailing stars on a full moon night."
Manievannan said that Yosemite Valley was flooded, allowing the rainbows to reflect even more. An edited long-exposure photo by Manievannan captured the bright stars and the lunar rainbows.
When most people think of rainbows, they think of the ones that follow rainstorms when lit by the sun. Rainbows form through a combination of light reflection and refraction inside water drops. In this case, the rainbows were created by light from the moon. Just like on a sunny day in the national park, moonlight can also be bent and reflected by the waterfalls.
The bright full moon provided the light reflection to create the dancing rainbows across the waterfalls.
