This intense fire rainbow appeared near Mount Rainier on July 26, 2016.

The Circumhorizontal arc was spotted by Jason Shipley in Mt. Rainier National Park.

The colorful sky phenomenon disappeared as quick as it appeared. That’s because to get this somewhat-rare phenomenon, the sun has to be higher than 58 degrees altitude in the sky.

This only happens around midday in the summertime in the Seattle area. Moreover, you need the right shaped ice crystal in the cloud aligned at just the perfect angle to the sunlight for the refraction effect to work.

So these “fire rainbows” (so nicknamed by appearance, not by having anything to do with fire or rainbows) are fairly rare sights in the mid-latitudes.
