A Circle of Purple Lights

This video comes from somewhere in the USA when someone noticed this
massive light formation, which was looking exactly like a big UFO hidden behind the clouds.

When the person saw it at the start, he thought it must be disco lights.

But when he realized and noticed the pattern, he started recording.

Also, the light was not coming from the ground, but directly from behind the clouds, making this huge UFO shape.

We can easily see the rays of lights.
