NASA astronaut Matthew Dominick photographed red sprites in Earth's upper atmosphere from the International Space Station on June 3, 2024. The bright red flashes (more easily seen by clicking on the photo to see a larger version) are a less understood phenomena associated with powerful lightning events and appear high above the clouds in the mesosphere. Transient Luminous Events (TLEs), including red sprites, are colorful bursts of energy that appear above storms as a result of lightning activity occurring in and below storms on Earth.

Crew members typically capture TLEs with wide focal lengths during Earth timelapses. Instruments mounted outside station, like Atmosphere-Space Interactions Monitor (ASIM)
