A Canadian photographer and aurora chaser shared a shot of a beautiful and rare sight.
Dar Tanner posted the photo on Twitter and Instagram showing what’s called a “moonbow” alongside the Northern Lights.
“The Moonbow is formed from a near full moon behind you lighting up the rain or moisture in the clouds in front of you,” Tanner wrote. “But to catch the Aurora dancing right through it was mind boggling! I love how the Big Dipper is right in the bow as well. One for the books for sure!”
The spectacular photo was taken in Castor, Alberta on Sunday night.
According to the Weather Network, “A moonbow is, essentially, a lunar rainbow which is seen at night, as the light from the Moon is backscattered by water droplets or raindrops.”
“Basically, moonlight is entering one side of a water droplet or raindrop, it is refracted off the inside surface of the opposite side of that droplet or raindrop, so that it exits out of the droplet or raindrop back in the direction from where it came, and then it is picked up by our eyes (or a camera).”
The month of October will be great for taking in celestial events, will two full moons (Including one on Halloween) and the Mars Opposition.
