Ball Lightning
Ball lightning,
or what appear to be ball lightning events, is
associated with
UFOs. Balls of colored light are often seen before, during, and after UFO
sightings, though not often reported due to the UFOs themselves always taking
center stage. Most sightings,
however, occur within close proximity of a
thunderstorm, but then many UFO sightings occur in the area of storms. What we
do know is not much.
Surprisingly,
A Brilliant Phenomenon

Visual sightings are often accompanied by sound, odor, and other natural and unnatural phenomenon. Most are accompanied by a loud humming. Sometimes ball lightnings are reported to emit a hissing sound. Many observers report a distinctive odor accompanying ball lightning. The odor is usually described as sharp and repugnant, resembling ozone, burning sulphur, or nitric oxide.
Many eyewitness accounts describe its movement as having the characteristics of an intelligence guiding it. It often enters structures through windows or doors, though it seems to have no difficulty passing through solid walls. It travels down hallways and up and down stairs and other lines of logical access and egress within structures. It pauses at objects and living things as though observing them. It has been described as similar to remote reconnaissance drones portrayed in science fiction movies.
A diameter of 6-18 inches is the most common size, although reports range from ½ inch up to 50 feet in width. They are luminous and spherical in shape and come in a rainbow of colors, often changing color many times during a single event. They do not seem to do a great deal of harm, although in their exits, they sometimes explode which can cause damage. They have even been sighted in aircraft flying in clear skies and on marine vessels without a cloud in sight.
Another oddity is that witnesses do not often detect heat and electricity even though ball lightning has been known to boil water. However, accounts of ball lightning which burned barns and melted wires do exist. Ball lightnings have also been observed to hang in mid-air far above the ground and have been observed falling from a cloud towards the ground.
Ball lightning and St. Elmo's fire are sometimes confused. St. Elmo's fire is a corona discharge from a pointed conducting object in a strong electric field. Like ball lightning, St. Elmo's fire may assume a spherical shape. Unlike ball lightning, St. Elmo's fire must remain attached to a conductor, although it may exhibit some motion along the conductor. Further, St. Elmo's fire can have a lifetime much greater than the lifetime of the usual ball lightning.
Ball lightnings decay in one of two modes, either silently or explosively. The explosive decay takes place rapidly and is accompanied by a loud noise. The silent decay can take place either rapidly or slowly. After the ball has decayed, it is sometimes reported that a mist or residue remains. Occasionally, a ball lightning has been observed to break up into two or more smaller ball lightnings.
The UK Royal Society's journal Philosophical Transactions outlines the current
state of knowledge of the puzzling phenomenon:
♦ The fireballs
last around 10 seconds in some cases.
♦The lightning
balls move around, sometimes downwards, sometimes upwards, sometimes indoors,
sometimes through glass.
♦
The
ball often disappears in an explosion, sometimes causing damage.
