Recordings of multiple sightings of the bright light also show the visible plume it left as it streaked down from the sky.
Beginning at around 2:45am on 20 January, Tweets were appearing with reports of an “explosion” and a glowing object falling from the sky. On the same day a video showing the meteor in high detail began to spread across the Japanese internet.
From the video we can easily see that this was no average meteor – this was a fireball.
