There were no reports of any injuries or damage such as those caused by the Russia meteorite, which sent out shockwaves that hurt some 1,200 people and shattered countless windows.
In a video from a state TV newscast posted on the website CubaSi late Friday, unidentified residents of the central city of Rodas, near Cienfuegos, said the explosion was impressive.
"On Tuesday we left home to fish around five in the afternoon, and around 8:00 we saw a light in the heavens and then a big ball of fire, bigger than the sun," one local man said in the video.
"My home shook completely," said a woman. "I had never heard such a strange thing."
Marcos Rodriguez, whom the video identified as a specialist in anthropology, said all signs point to a meteorite.
A reporter said a similar phenomenon was observed in 1994 elsewhere in Cienfuegos province.
The video said Cuban authorities were looking for any fragments that may have fallen to the earth.
