Overview

• Security and dashboard cameras across Kyushu captured the flash around 23:08 local time on August 19.
• Residents in Kagoshima reported a loud boom consistent with a supersonic breakup, and officials reported no injuries or damage.
• Japanese and international specialists estimate the object was roughly 10 meters in space and say it most likely fell into the sea south of Kyushu.
• Authorities and observation networks are compiling videos and witness accounts to triangulate the trajectory, estimate speed and mass, and check for any fragments, with none recovered so far.
• Researchers cite Chelyabinsk as a calibration reference and note the event’s records will aid impact-risk modeling and near-Earth object detection.
