those look like sprites, but I thought sprites went up from the top of the clouds.

Sprites are lightning related phenomenon (electrical). This is in the category of rainbows, halos and sun dogs (refracted sunlight).

...actually refraction and reflection. Refraction is responsible for the different colors.

In that case, they are very strange indeed. Very beautiful, but very strange.

thanks for clarifying what sprites are.
