Blitzortung.org is a worldwide citizen science network of lightning detectors. A map displaying lightning strikes in real-time can be found at https://www.blitzortung.org/en/live_lightning_maps.php Unlike other lightning maps, this map also shows which detectors reported the strike. Surprisingly, strikes can be detected from halfway around the world. Information about the technology and how you can participate can be found on their forum: https://www.blitzortung.org/en/forum.php
