Ufo Classification System

HYNEK Request Structure

In the history of UFOlogy, the most authoritative facet in classifying UFO sightings was Dr. Joseph Allen Hynek. A tutor of astronomy at NorthWestern The academy, Dr. Hynek gave UFOlogy educational honesty by recognizing that sighting reports were its major bringer of data.

Hynek branched accounts participating in two types: nation where the witnesses was higher than five hundred feet from the object and nation where the witnesses was smaller number than five hundred feet from the object - so called clammy encounters.

He fashioned the first category of UFO sighting consists of three different types;

1. Night LIGHTS - these are lights in the sky that cannot be accounted for by pretend craft, meteorological or above what is usual phenomena;

2. Brightness DISCS - these are end craft, not essentially disc-shaped, that cannot be accounted for by pretend craft;

3. RADAR Lifelike - these are unusual readings on an electronic machine, not essentially radar that cannot be explained by any pretend phenomena.

The gleam category classified as clammy encounters, is branched participating in six types:

1. Unfair ENCOUNTERS OF THE Young Kind (CE1) - the witnesses gain recognition here five hundred feet of an unusual object; but it has no phone call everyday in the witnesses of the background.

2. Unfair ENCOUNTERS OF THE Spare Kind (CE2) - the witnesses comes here the five hundred feet of an unusual object that grass a variety of overexploit or environmental evidence in the background.

3. Unfair ENCOUNTERS OF THE THIRD Kind (CE3) - the alien beings are seen hidden or clammy to the object, and who may or may not restrain a variety of contact in the meet.

4. Unfair ENCOUNTERS OF THE FOURTH Kind (CE4) - the meet hardened emotional or environmental involve due to direct phone call in alien beings.

5. Unfair ENCOUNTERS OF THE FIFTH Kind (CE5) - the meet can give an undertaking encounters by contacting aliens really or morally.

6. Unfair ENCOUNTERS OF THE SIXTH Kind (CE6) - the meet is possessed by a non-physical alien item

The last three categories (CE4, CE5, CE6) were not exceptionally included in Hynek's order system equally he was mocking about abduction accounts. He did not predilection that communicate was loads end evidence in abduction reports.

Thus far, while Hynek died in 1986, a new social group of UFOlogists has made whole use of these alien classifications.
