On May 15th, 2026, a meter-sized asteroid 🪨 was discovered before it entered the atmosphere between Australia and Micronesia.
2026 JN4 turns out to be the 12th asteroid to be discovered before becoming a meteor ☄️, even if the meteor itself has not yet been detected...

Bad luck: when 2026 JN4 was discovered, on May 15th, 2026, the Sun was rising above the United States, making the follow up of the small asteroid hard to organize! A few hours later the same day, around 13h 40min UT, only 6 observations of it were completed before the object entered the atmosphere,....

🛑 ASTEROID ATMOSPHERIC ENTRY ALERT 🛑

IF CONFIRMED, a freshly discovered small (~1,1 m diameter) asteroid (ST26E86) is in a trajectory that will direct it into the Earth atmosphere, in a region extending from North-Western Australia to Micronesia, and passing over the North of Papua New-Guinea (May 15) around 13h 42min UT. No real impact, but a very bright and slow fireball should be observable by people in the area, and meteorites may reach the ground.
Stay tuned for more updates!

UPDATE: After 6 observations, the atmospheric entry was confirmed and predicted to occur at 13h 36min UT at position: lat. = 8.62476° S ; long = 137.34220 E
