Hello [First name], I am so sorry for answering so late. According to your report, this does match quite well a "SkyTracer", a projector system used at parties or in discotheques. Best regards Patrick Gross |

One sometimes call them "discotheque lasers", it is often so in the regional Pres, as a cause of UFO sightings. They are actually not lasers but projectors of ordinary light. The purpose of these Skytracers is to get attention from far away, up to miles away. Lasers are mostly effective on location, inside a nightclub or on a concert place. |
|
|
Their light can be white, but it can also have a green, blue, red, yellow hue... Motors are used to move the projections on 1, 2 or 3 axis. By software, they can be programmed to perform sequences of more or less repetitive figures; as witnesses often report. |
|
|
When there is vapor in the air from the ground up, the Skytracer produces a beam of light, fixed or mobile. It can produce the impression of a "luminous cigar." |
|
|
But id a low cloud layer tops a mass of dry air on the ground, there is no visible beam, one sees the projection of the beam on the bottom of the clouds. It is mostly in such conditions that people sometimes are unable to recognize projectors. With several networked and programmed Skytracers, it is possible de produce shows of the "flying saucer" or "flying saucers formation" kind. |
