On April 2nd, high above a thunderstorm in the Czech republic, an enormous ring of light appeared near the edge of space. Amateur astronomer Martin Popek photographed the donut-shaped apparition using a low-light video camera

"It appeared for just a millisecond alongside the constellation Orion" says Popek. 

This is an example of an ELVE (Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources). First seen by cameras on the space shuttle in 1990, ELVEs appear when a pulse of electromagnetic radiation from lightning propagates up toward space and hits the base of Earth's ionosphere. A faint ring of light marks the broad 'spot' where the EMP hits. 

ELVES often appear alongside red sprites. Indeed, Popek's camera caught a cluster of sprites dancing nearby the ~100 km ring.
