The Kagoshima Local Meteorological Observatory reported that sensors on Sakurajima detected a sonic wave at around 11:08 p.m., coinciding with the moment the light was seen in the sky. The flash was confirmed at several sites across Kagoshima Prefecture, and officials said the phenomenon was most likely a fireball or meteorite. Maeda Toshihisa, director of the Sendai Space Museum in Satsumasendai City, noted that the burst of light was so intense it briefly illuminated Sakurajima at night, adding that he believed it to be a fireball, one of the brightest classes of meteors.
