Yi first spotted the UFO on the evening of October 5, but was only able to take a low quality cell phone photograph of it. In hopes that the UFO would return, the next night Yi was prepared with a video camera to record the object.
Luckily, Yi was right, and the object did return. He was able to get a few minutes of video before the object disappeared. Yi says the object could be seen for about 10 to 20 minutes before disappearing.
As is common with auto-focus, the focus goes in and out, and when out of focus the object appears to be diamond shaped. This is an effect of the aperture, and does not reflect the true shape of the object. via openmindstv , smileboyahk
