Perseid Fireball and Persistent Train

Before local midnight on August 12, this brilliant Perseid meteor flashed above the Poloniny Dark Sky Park, Slovakia. Streaking beside the summer Milky Way, its initial color is likely due to the shower meteor's high speed. Moving at about 60 kilometers per second, Perseid meteors can excite green emission from oxygen atoms as they pass through the thin atmosphere at high altitudes. This Perseid left a lingering visible train, characteristic of bright meteors.
