Abstract

The article focuses on the record-breaking lightning event that occurred on October 22, 2017, which is now recognized as the longest single flash of lightning ever recorded, spanning 829 kilometers and lasting 7.39 seconds. This megaflash, identified through a reanalysis of satellite data, is part of a rare phenomenon that occurs in only about 1 in 1,000 thunderstorms in the Americas. The event originated from a significant thunderstorm system in the central United States and produced at least 116 cloud-to-ground lightning strikes. Researchers are investigating the conditions that lead to such megaflashes, as understanding their formation is crucial for public safety due to their potential to trigger wildfires and impact large areas.
