its a ball of lightning guys xD that building is probably the highest point
Ball lightning is a proposed atmospheric electrical phenomenon of which little is known. The term refers to reports of luminous, usually spherical objects which vary from pea-sized to several meters in diameter. It is usually associated with thunderstorms, but lasts considerably longer than the split-second flash of a lightning bolt. Many of the early reports say that the ball eventually explodes, sometimes with fatal consequences, leaving behind the odor of sulfur. There are records of free-floating glowing balls that occur in total absence of thunderclouds. This occurs commonly in the valley of Hessdalen, Norway.[1] One recent theory suggests that these light balls (Hessdalen Lights) are produced by the ionization of air and dust by alpha particles during radon decay in the dusty atmosphere.[2]
Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon. Scientific data on natural ball lightning are scarce owing to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and has therefore produced somewhat inconsistent findings. Given inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown.[3] Until recently, ball lightning was often regarded as a fantasy or a hoax, but some serious scientific discussions and theories have attempted to explain it. Descriptions of ball lightning vary wildly. It has been described as moving up and down, sideways or in unpredictable trajectories, hovering and moving with or against the wind; attracted to,[27] unaffected by, or repelled from buildings, people, cars and other objects. Some accounts describe it as moving through solid masses of wood or metal without effect, while others describe it as destructive and melting or burning those substances. Its appearance has also been linked to power lines[28] as well as during thunderstorms and also calm weather. Ball lightning has been described as transparent, translucent, multicolored, evenly lit, radiating flames, filaments or sparks, with shapes that vary between spheres, ovals, tear-drops, rods, or disks.[29]
Ball lightning is often erroneously identified as St. Elmo's fire. They are separate and distinct phenomena.[30]
The balls have been reported to disperse in many different ways, such as suddenly vanishing, gradually dissipating, absorption into an object, "popping," exploding loudly, or even exploding with force, which is sometimes reported as damaging. Accounts also vary on their alleged danger to humans, from lethal to harmless.
