Huge record-breaking lightning bolt spans 3 U.S. states:

It's not quite the right time to debunk that myth about lightning never striking the same place twice, as an enormous bolt has set a new global record.

The longest single flash of lightning has been captured by satellites of the National Oceanic and Atmospheric Administration, recorded and announced by the U.N.'s World Meteorological Organization on Tuesday.

The "megaflash" stretched 768 kilometres (give or take 8 kilometres) or 477.2 miles (give or take 5 miles) across parts of the southern U.S. including Texas, Louisiana, and Mississippi on April 29, 2020.

The flash in question measures as long as the distance between New York City and Columbus Ohio. Or if you want another, between London and Hamburg.

[...] If the WMO isn't cranking up AC/DC's "Thunderstruck" today, they're doing it wrong.

    Not as amazing as SoylentNews banning aristarchus over all United States, European Unities, and Central and South America, Asia, Northern East Asia, and Australia and New Zealand. But, you know, these things are relative. Upmod old aristarchus posts if you can, and bring back our brother.

      Oh, Spam modding innocent ACs pointing out the censorship inherent is the system, now, are we? Offtopic, at most, but hardly spam, unless you think a post by a fellow soylentil, worried about the censoring of a fellow solylentil, is "spam". In that case, may Slashdot-beta have mercy on your soul.

      How do you know he didn't get who he was aiming for? There are a lot of potential targets in Texas, Louisiana, and Mississippi (about 0.6% of the population according to https://www.hli.org/resources/number-of-transgenders-in-the-united-states/) [hli.org]

    There was also this:

    he greatest duration for a single lightning flash of 17.102 ± 0.002 seconds from the flash that developed continuously through a thunderstorm over Uruguay and northern Argentina on 18 June 2020.

    I wonder how much energy was transferred by that lightning strike. It probably wasn't transmitting anywhere near peak for all but a very small fraction of that lifespan, but that's still a huge amount of energy possible.

    As to that amazingly long strike, it seems to me that there had to be special circumstances otherwise the lightning (on either end) would have arced to something closer, like the ground. Perhaps it was a cloud to cloud strike with heavily ionized air in between. Ionization greatly increases the conductivity of air. It might also be higher altitude, perhaps stretching well above the cloud tops - low density helps prolong ionization. Finally, how do you generate a large net difference in voltage between two parts (presumably of the same extended storm system) separated by a large horizontal distance? What I recall of lightning dynamics is that the difference is generated vertically.

    But perhaps in my budding scenario, there were a line of thunderstorms, creating a huge channel of ionized air above the storms, and one end had discharged to ground (or elsewhere) and the other end was highly charged. It was lower resistance to travel through the ionized channel to the discharged side than to arc directly to ground underneath.

    What potential difference could create an arc that long? TFA does not contain the word "volt".

      Runaway in Texas and Zumi in Mississippi would be enough to do it.
