Dashcams from many vehicles caught the scene and netizens quickly went to twitter to describe what they saw.
"I could see it clearly in Chum Phae district, Khon Kaen province. It's moving west," said @Libpon on her Twitter account sent to JS100.
"I saw it on the expressway on my way to the Rama II exit, too," said @Kinokim_knk on another account.
The Thai Astronomical Society Facebook page was so overwhelmed with questions that it had to put out a lengthy question and answer section, explaining that the bright light was a likely fireball, a very bright meteor caused by a meteoroid. Since it likely burned up completely, it was probably not a meteorite.
