The recent sighting of what appears to be an unidentified flying object (UFO) over Thai central province of Ayutthaya has left witnesses scratching their heads over what exactly it might have been while some astronomer and experts thought it was something like a meteor.

Morakot Areeya, head of a astronomy learning center, was quotedon Monday by the Bangkok Post as saying that he saw a burning object speeding across the sky at about 6:20 p.m. (1120 GMT) on March 4 in Ayutthaya's Nakhon Si Ayutthaya district. Some other witnesses also reported they have seen the unidentified object that night.

Worawit Thanwuttibandit, a cosmic adviser to the Thai Astronomical Society, said the object might have been a large meteor.

Dr Sarun Posayajinda, deputy director-general of the National Astronomical Research Institute, said it was possible that the object was some kind of space debris which had burst into flames on entering the earth's atmosphere.

Morakot took a photograph of the object, which he first thought was an airplane that had burst into flames. However, he was surprised to see the object continue to streak across the sky in an easterly direction before disappearing from sight.

Morakot said it did not appear that the object had struck the earth, rather it had traveled almost horizontally. He said some locals felt the object may have been some form of UFO.

"It is strange because after contacting a number of local amateur radio hams, none had learnt of any air crashes in the area," Morakot said
