((NUFORC Note: This report seems strongly suggestive of the new four-light, rotating advertising lights. We have proposed this possibility to the witness, and are awaiting a response. This type of advertising light, somewhat new in the U. S. market, may be new to the Asian market. It has caused many reports from the U. S., as well.))4 oval white lights circulating in the night sky.I did not see how it began. My wife alerted me and others to see some moving lights in the sky while all of us were at my house balcony. 4 oval lights were seen circulating in a constant circle, each of the light would travel a quarter of the circle and all the 4 of them would merge together with one another (overlapping) at the center of the circle (circular path). It was just a moment after they merge that they dispersed and circulated again. They took about 2 seconds to complete one cycle. I took serveral photos of the sighting using a normal camera, but i am not sure whether the lights could be seen upon development of the film. The lights were oval in shape and white in colour. It seemed like someone have used a very powerful spotlight to shine it into the sky, but there was no beam/spectrum from the source of the light. The sky and the moon was covered with some clouds. The lights were not flying in the clear sky. They seemed to be flying among the cloud. It was about 15 minutes later where they disappeared. All the 4 lights have merged together before flying away from us. Their flying away was fater than the speed of lighting. In the midst of our observation, i have noticed a plane flying past the phenomenon. I will email the images upon development of them.
