Nov. 4-5 marks the expected peak of the Southern Taurids' fireball swarm, offering one of autumn's best chances to see exceptionally bright meteors overnight Wednesday and Thursday.
NASA defines fireballs as meteors at least as bright as Venus, and the shower's flashes occur when debris from Comet 2P/Encke burns up in Earth's atmosphere.
Around midnight should offer the best viewing as Taurus climbs higher in the eastern sky, though the Southern Taurids' broad peak means watchers do not need exact timing.
The shower produces only a handful of meteors per hour, far fewer than the Geminids' potential 120 per hour, but it is followed by the Northern Taurids on Nov. 11-12 for another fireball-rich display.
