![]() Physicist Emeritus Professor Brian Tanner and historian Giles Gasper of Durham University identified the chronicle entry as probably describing ball lightning, and noted its similarity to other accounts: He states, "A marvellous sign descended near London", consisting of a dense and dark cloud, emitting a white substance that grew into a spherical shape under the cloud, from which a fiery globe fell towards the river. The chronicle of Gervase of Canterbury, an English monk, contains what is possibly the earliest known reference to ball lightning, dated 7 June 1195. Another study analyzed reports of 10,000 cases. ![]() Historical accounts īall lightning is a possible source of legends that describe luminous balls, such as the mythological Anchimayen from Argentinean and Chilean Mapuche culture.Īccording to statistical investigations in 1960, ball lightning had been seen by 5% of the population of the Earth. Owing to the lack of reproducible data, the existence of ball lightning as a distinct physical phenomenon remains unproven. The presumption of its existence has depended on reported public sightings, which have produced inconsistent findings. Scientists have proposed a number of hypotheses to explain reports of ball lightning over the centuries, but scientific data on ball lightning remain scarce. Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but how these relate to the supposed phenomenon remains unclear. An optical spectrum of what appears to have been a ball lightning event was published in January 2014 and included a video at high frame rate. Descriptions of ball lightning appear in a variety of accounts over the centuries and have received attention from scientists. Some 19th-century reports describe balls that eventually explode and leave behind an odor of sulfur. Though usually associated with thunderstorms, the observed phenomenon is reported to last considerably longer than the split-second flash of a lightning bolt, and is a phenomenon distinct from St. For the Chinese novel, see Ball Lightning (novel).īall lightning is a rare and unexplained phenomenon described as luminescent, spherical objects that vary from pea-sized to several meters in diameter. Similar lights spotted over San Diego and Tijuana in June 2022 were reportedly flares being used for a military exercise, according to San Diego police, but the military never confirmed.For the Czech film, see Ball Lightning (film). ![]() It's not the first time strange sightings have sent the internet searching for answers. NBC 7 has not yet heard back from the Navy. Air Force was conducting drills in the area but NBC 7 has been unable to verify that with the Air Force. The Coast Guard told NBC 7 they believed the U.S. Coast Guard to see if there were any drills Monday evening. Several commenters theorized that the sighting was military-related. Shanmugam said it left a small streak and a glow behind. It was almost like, I wouldn't say it flew away, it just blipped." ![]() And these lights were four big rectangles and almost like pulsating." "It was just hovering for about a good two minutes. "It was such a bright light, you cannot miss it in the sky," Shanmugam described. A board member from the Mutual UFO Network says it's an exciting development. It's not a confirmation that aliens exist - just an admission that aerospace experts can't determine what they saw. Next month, Congress is expected to receive a military report that details several sightings of unidentified flying objects. ![]()
