UFO. Netherlands

Most often, this category can be attributed to the lights of a crane, high-rise buildings, boiler pipes, etc., equipped with nighttime lighting that is visible through the haze, fog, or when the color match between the support and the color of the surrounding space.

For unexplained may be taken accidentally or deliberately issued when shooting photos and video. A feature of the lights of a construction crane (in contrast to the street lights) is the movement of the boom, which is a light source.

Bright Sun breaking through the clouds can be mistaken for UFOs. This version also includes various celestial bodies (Sun, Moon, stars), whose fragments are visible through uneven cloud, and the reflection of light from them on the clouds, which may be perceived as separate objects.

Crepuscular rays - the name of the rays of sunlight that pass through gaps in clouds or other objects to form the visible "light pillars" or "waves". Crepuscular rays are visible due to the fact that the region of space with sunlit air separated clearly from the shaded space.

In many cities (especially European) are widely distributed street lights, weighing on an extension wire. Sometimes, when photographing a landscape, a lantern in the sky can be mistaken for a UFO if the wires will not be visible (e.g. under a certain angle).

It happens that the author deliberately blurs the wires.

Sometimes these lights are used for an intentional imitation of a UFO due to osobennostei design.

Sometimes a UFO can be taken lights caught in the frame part, or as a contrast object against a plain background when shooting at night.
