In 1837 a entire dialogue of lightning seemed within the Annual of the French Bureau des Longitudes with a bit on ball lightning which supplied for the 1st time a on hand resource within the medical literature of the fundamental homes of this curious common phenomenon. the writer, Francois Arago, used to be the dominant impact within the French Academy of Sciences within the 19th century, having join that august physique on the age of twenty-three. His recognition on my own without doubt served at the moment to set up the validity of clinical curiosity within the challenge. additionally his dialogue coated a number of the significant questions linked to ball lightning in a nota­ bly clear-sighted, potent kind. Later reconsideration of a similar questions frequently supplied no major development over Arago's dialogue. There a dauntless band of various yet constantly small quantity who tried to account for an it appears uncomplicated typical incidence, a ball of fireplace often noticeable in thunderstorms, with the simplest wisdom that advancing technological know-how may supply. All makes an attempt to house this phenomenon have been in­ variably annoyed. The features of ball lightning should be quite simply cataloged, yet they firmly resisted either experimental copy and theo­ retical clarification. One might say that to at the present time there is not any rationalization accredited by way of various scientists. numerous investigators of serious skill and enormous accomplishment in several fields of technological know-how, together with Faraday, Kelvin, and Arrhenius, took observe of the problem.

In some descriptions(465, 518) it has been classified as entirely harmless, potential danger being attached only to the ordinary linear flash of lightning often reported as preliminary to appearance of the ball or occurring immediately as it vanishes. Observations of Ball Lightning 45 In 1904, a German engineer who had briefly seen ball lightning at a great distance ten years earlier was walking with his wife in a storm with rain, hail, and snow while a strong wind blew. (50) They saw a large bright ball 4 m in diameter and 6 m above the ice at a distance of approximately 30 m from the road which they were following.

It disappeared, evidently by turning in a private gateway. The witness reported he had decided almost immediately that the image was entirely subjective from the effect of the initial flash of lightning on his retina, following the direction of his eye as he walked and disappearing when the effect on the retina wore off. The illusion most often proposed is attributed to the viewer observing an ordinary flash of lightning while directly in its path. Since he sees only the crosssection of the flash, it appears to be a round lightning mass traveling toward him, assuming that no change in direction occurs, as it does in the common zigzag path.

During calm drizzling weather a 15- to 20-cm-diameter lightning ball was seen in 1956, after it rolled down a tree. (384) No ordinary lightning was noted during this time. The tree was marked by a very weak trace unlike that often produced by zigzag lightning. The ball appeared bluish-white at 300 m from the observer, then red when at 2 m. It was seen falling slowly at an angle of 30° ; it then bounced off the wet meadow up to 4 m and moved slowly along a barn. It circled a tree and hit a fence post with a loud explosion.
