A system used to categorize the various types of UFO and paranormal experiences invented by Dr. Jacques Vallee and is now used more often instead of the Hynek Scale of UFO Classification since it gives the reader a more detailed summary of a case. The categories are as follows.
AN RATING: Classifies any anomalous behavior.
AN1: Anomalies which have no lasting physical effects. i.e. amorphous lights, unexplained explosions.
AN2: Anomalies which do have lasting physical effects. i.e. poltergeists, materialized objects, areas of flattened grass, corn circles.
AN3: Anomalies with associated entities. i.e. ghosts, yetis, spirits, elves and other mythical/legendary entities.
AN4: Witness interaction with the AN3 entities. i.e. near-death experiences, religious miracles and visions, OBEs (out-of-body experiences).
AN5: Anomalous reports of injuries and deaths. i.e. SHC(spontaneous human combustion), unexplained wounds as well as permanent healing that results from a paranormal experience.
MA RATING: Describes behavior of a UFO. It is analogous to the Nocturnal Light, Daylight Disk, and Radar Visual classifications.
MA1: A UFO has been observed which travels in a discontinuous trajectory. i.e.vertical drops, maneuvers or loops.
MA2: MA1 plus any physical effects caused by the UFO.
MA3: MA1 plus any entities observed on board. i.e. the airship cases of the late nineteenth century.
MA4: Maneuvers accompanied by a sense of reality transformation for the observer.
MA5: A manoeuvre that results in a permanent injury or death of the witness.
FB RATING: Fly-by rating.
FB1: A simple sighting of a UFO traveling in a straight line across the sky.
FB2: FB1 accompanied by physical evidence.
FB3: A fly-by where entities are observed on board (rare).
FB4: A fly-by where the witness experienced a transformation of reality into the object or its occupants.
FB5: A fly-by which the witness would suffer permanent injuries or even death.
CE RATING: Close Encounter rating. Similar to the Hynek Close Encounter ratings.
CE1: UFO comes within 500' of the witness, but no after effects are suffered by the witness or the surrounding area.
CE2: A CE1 that leaves landing traces or injuries to the witness.
CE3: Entities have been observed on the UFO.
CE4: The witness has been abducted.
CE5: CE4 which results in permanent psychological injuries or death.
SVP RATING: The all-important credibility rating."Marks" out of four are given for the three categories of source reliability (first digit), site visit (second digit) and possible explanations (third digit). A rating of 222 or higher indicates the case was reported by a reliable source, the site has been visited and a natural explanation would require a major alteration of at least one parameter.
SOURCE RELIABILITY RATING:
0: Unknown or unreliable source.
1: Report attributed to a known source of unknown or uncalibrated reliability.
2: Reliable source,secondhand.
3: Reliable source, firsthand.
4: Firsthand personal interview with the witness by a source of proven reliability.
SITE VISIT RATING:
0: No site visit, or answer unknown.
1: Site visit by a casual person not familiar with the phenomena.
2: Site visited by persons familiar with the phenomena.
3: Site visit by a reliable investigator with some experience.
4: Site visit by a skilled analyst.
POSSIBLE EXPLANATIONS RATING:
0: Data consistent with one or more natural causes.
1: Natural explanation requires only slight modification of the data.
2: Natural explanation requires major alteration of one parameter.
3: Natural explanation requires major alteration of several parameters.
4: No natural explanation possible, given the evidence.
