Sprites narxes posted:4/5/2011 4:44:51 AM Transient Luminous Events Large thunderstorms are capable of producing other kinds of electrical phenomena called transient luminous events (TLE's). The most common TLE's include red sprites, blue jets, and elves.Red Sprites can appear directly above an active thunderstorm as a large but weak flash. They usually happen at the same time as powerful positive CG lightning strokes. They can extend up to 60 miles from the cloud top. Sprites are mostly red and usually last no more than a few seconds, and their shapes are described as resembling jellyfish, carrots, or columns. Because sprites are not very bright, they can only be seen at night. They are rarely seen with the human eye, so they are most often imaged with highly sensitive cameras.Blue jets emerge from the top of the thundercloud, but are not directly associated with cloud-to-ground lighting. They extend up in narrow cones fanning out and disappearing at heights of 25-35 miles. Blue jets last a fraction of a second and have been witnessed by pilots.Elves are rapidly expanding disk-shaped regions of glowing that can be up to 300 miles across. They last less than a thousandth of a second, and occur above areas of active cloud to ground lightning. Scientists believe elves result when an energetic electromagnetic pulse extends up into the ionosphere. Elves were discovered in 1992 by a low-light video camera on the Space Shuttle.Relation with UFO sightings. Not meany poeple know of this phenomena, and im posting this article just to make some of you aware of these things they exicst and are quite rare. It might just explain some of the ufo sightings, dont just belive but be sceptic its important to have a clear look on things. and ofcourse there is more out there what we havent discoverd yet. Im looking for ward to it. spiritech0 posted:4/5/2011 2:18:11 PM So... in 1992 the spacemen had video cameras that can clearly record and detect things measured in less than a thousandth of a second that appear constantly in an expanding manner to a radius of 300 miles... What DO they record in 2011..? Maybe me when I'm on the commode three miles down? No? This tech is about as useful as my favorite kaeidescope, the Hubble.I'm just kidding.
