So-called superbolts are at least 100 times brighter than ordinary lighting, but can be more than 1,000 times brighter. Peterson said researchers care about the brightness of lightning because the more luminous flashes, from a satellite perspective, are usually the most powerful. But a few ordinary bolts at the periphery of storms may protrude into clear air in direct view of the sensor, tricking the satellite into thinking an exceptionally bright flash has occurred. “This can lead to these superbolt cases,” Peterson said. This is many times hotter than the surface of the sun. (Image: © Shutterstock) Superbolts … Because of that, it’s easier to build up more charge in the storm and generate a stronger electric field. But superbolts are also super-rare, occurring only about five times in 10 million flashes, Turman wrote in the study. No doubt about it. Lightning striking the sea near Fort St. … The study was led by Michael Peterson, a scientist at Los Alamos National Laboratory in Los Alamos, N.M. His team examined two years’ worth of data from the GOES weather satellites, which peer down on North and South America with ultrahigh resolution. “One unresolved question, however, was whether these superbolts were a different kind of lightning, or if they were just normal lightning seen directly by the spacecraft.". Scientists have confirmed the existence of ‘superbolts’ that can be up to 1,000 times brighter than the average lightning strike, producing more power than all solar panels and wind turbines in the US combined. Still, Peterson said that lightning scientists have been privy to a “fire hose” of data since the first Geostationary Lightning Mapper was launched via satellite in 2016. The newly-published paper found roughly 0.3 percent can be classified as a superbolt – defined as any lightning flash 100 times brighter than average. Peterson’s work describes ordinary superbolts as “ubiquitous” and notes that they can occur with just about any strong thunderstorm in North or South America. A microsecond is one millionth of a second. Others lightning researchers, like Joseph Dwyer at the University of New Hampshire, say that Peterson’s work clarifies uncertainties in superbolt theory dating back decades. The brightest superbolts tended to cluster in geographic regions where large thunderstorms are common, and superbolt appearance was associated with "long-horizontal lightning flashes that can span hundreds of kilometers, which have been recently termed 'megaflashes,'" Peterson said. Live Science is part of Future US Inc, an international media group and leading digital publisher. Earlier this year, researchers confirmed a pair of ultra-long-distance lightning strikes in South America that spanned up to 442 miles and lasted for nearly 17 seconds. A superbolt is any flash of lightning that is 100 times brighter than average. They’re so intense that, about four decades ago, a scientist had to coin a new word to describe them: Superbolts! The pellets in a 00 (always said as “double-ought”) shell are each about the size of a .38 Special bullet. “You have these events that are very instantaneous, tens to hundreds of microseconds, and then they’re over,” explained Peterson. Lightning is incredibly powerful. Lightning data for that study came from observations by Vela satellites, which were launched in 1969 to detect nuclear explosions from space, and operated until 1979, according to NASA. Superbolts that appeared over the ocean were fueled by the gradual buildup of electrical charges in the stormclouds, so it wasn't surprising that bolts would be more powerful when all that electricity was eventually released, according to the study. The scientists found that superbolts could emanate from electrical pulses between clouds, as well as from cloud-to-ground pulses.

Superbolts — flashes of lightning that are up to 1,000 times brighter than average — really do exist, two new studies confirm. Not all detected superbolts were actually that super, however. “[The satellites] will tell you there is something bright there,” explained Peterson.
