Discussion of potential infrasound detections of #2026JN4 impacting the atmosphere: https://groups.io/g/mpml/topic/119347036.

It looks like figuring out exactly where this one landed will have to await the release of satellite flash monitoring.

It's still rare for an #asteroid to be detected on impact trajectory. Bigger shooting stars at night are mostly missed opportunities. As a #spacegeek but not an astronomer, I'm not in their discussions. So I noticed it on a monitor on my wall. It mostly displays aircraft activity around PDX and the Pacific Northwest. But 2 panels are space related, my own software, using NOAA aurora & NASA asteroid data. #2026JN4 stood out as a blue line on the close asteroid passes. #astronomy #LowFlyingRocks

#2026JN4 asteroidea atzo sartu zen Lurreko atmosferan Papua Ginea Berrian. 1,5 metro inguruko diametroa zuen. Sartu baino 5 ordu lehenago aurkitu zuten.

#asteroid #2026JN4 is apparently not being added to the official list of pre-impact detections because there were not enough observations to nail down an estimated impact point and there were no reports to confirm air or ground impact. More observations could change that. (ref @michael_w_busch ) https://mastodon.online/@michael_w_busch/116581727698756513 #astronomy #PlanetaryDefense #PlanetaryDefence #LowFlyingRocks

At approximately 2026-May-15 13:44 UTC, #asteroid #2026JN4 impacted Earth's atmosphere shortly after discovery. The 1m-wide rock was not a threat. Most that size are simply not discovered before becoming a common fireball meteor. The previous impactor discovered before impact was in December 2024. https://ssd.jpl.nasa.gov/tools/sbdb_lookup.html#/?sstr=2026%20JN4&view=OPC #astronomy #PlanetaryDefense #PlanetaryDefence #LowFlyingRocks
