Witnesses report a point or blob of light with no discernible structure. Often described as white, orange, or multicolored — and capable of sudden directional changes or rapid acceleration.
Large, silent triangular craft observed at low altitude. Typically feature lights at each corner and a center light, moving slowly or hovering before disappearing at high speed.
A perfectly round object, often metallic or luminous, moving in ways inconsistent with conventional aircraft. Frequently reported over populated areas and near military installations.
The classic "flying saucer" shape — a flattened disc, sometimes with a central dome. Often seen hovering before executing abrupt maneuvers impossible for known aircraft.
Multiple objects flying in coordinated patterns — V-shapes, triangles, or grid arrangements. Movements are synchronized in ways that suggest either one craft or centralized control.
Luminous object resembling a meteor but exhibiting controlled flight behavior. May slow, change direction, or split into multiple objects before disappearing.
Sightings that do not fit standard shape categories, or where the witness could not determine a clear shape. Includes amorphous, changing, or indescribable objects.
Elongated, cylindrical object with no visible wings or exhaust. Often silver or metallic in daylight, sometimes lit at both ends. Associated with high-altitude transit.
Four-sided craft with a pronounced angular profile, often with lights at each point. Less common than other shapes but consistently described across multiple states.
An egg or oval shaped craft, intermediate between sphere and disk. Frequently reported with pulsing or rotating lights along its perimeter.
Large rectangular or boxy craft, sometimes reported as resembling a lit office building in the sky. Associated with slow, deliberate movement at low altitude.
A flat, circular object distinct from spheres by its two-dimensional appearance from below. Sometimes described with a rotating outer ring and stationary inner section.
V or boomerang-shaped craft, resembling a stealth aircraft but typically silent and much larger. Often confused with triangle reports at distance.
A tube-shaped object, similar to a cigar but more uniformly cylindrical. Sometimes reported as transparent or translucent with internal illumination.
A teardrop or droplet-shaped craft, with the pointed end typically facing the direction of travel. Occasionally reported descending vertically before vanishing.
Cross or plus-sign shaped craft, often with a light at each terminus. Rare shape reported primarily in the central and eastern United States.
