During this period the moon will reach its full phase on Sunday May 31st. At that time the moon will lie above the horizon all night long. As the week progresses, there will be a limited amount of time between dusk and moonrise when the sky will be dark enough for meteor observing...

On May 15th, 2026, a meter-sized asteroid πŸͺ¨ 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 β˜„οΈ, 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,....

πŸ›‘ ASTEROID ATMOSPHERIC ENTRY ALERT πŸ›‘

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. = 8.62476Β° S ; long = 137.34220 E
