These pictures of the night sky were taken while teaching in Pua in Nan Province in Northern Thailand in December 2008. In fact, at this specific time I was talking on the telephone with a friend in London. Apart from this no one else was around to hear or see what I had witnessed. UFO's or, Thai paper lanterns?
