   Red Sprites and Circular Elves Lightning over Italy

   Lightning comes in various forms, including white flashes between clouds, red sprites with tentacles, and ringed ELVES. Sprites are brief but bright, while ELVES form glowing nitrogen rings in the ionosphere. Capturing both together is rare, as seen in a video from Italy over the Adriatic Sea.
