This green disk was caught off guard when the suns reflection was at the wrong angle and the cloaked UFO was revealed for a few seconds. This happens a lot during sunset, but the clouds caused a false sunset like state and the UFO was seen. You can clearly make out the round disk with the raised center and what looks like a steam from the top of the craft. A similar UFO was caught in the aurora borealis several years back with the same shape, that other sighting confirms that this is an alien craft. SCW
The Groningen blogger Harry Clipperton likes pictures of nature. On Tuesday he walked along a path in Onlanden, the border between the provinces of Groningen and Drenthe.
At home Groningen looked at his pictures and then discovered a UFO. Clipperton writes on his blog: Suddenly something flashed. At first I thought my device, but the flitskap was not up. There was not a drop on my lens. I decided it must have been lightning. But at home I see something strange in one of the photos that I made at the end of the lane trees. “
The UFO is, as the word implies, still unidentified. Whether it is a meteorological phenomenon, a meteor, a flying saucer or something else, is not yet clear.
