Comprehensive Lecture on Transient Luminous Events (TLEs) 

December 4th, 2024, Spritacular Citizen Scientist Captures Photo of Elusive Upper Atmospheric Electrical Phenomena Over Château de Beynac. A flash of lightning, and then—something else. High above a storm, a crimson figure blinks in and out of existence. If you see it, you are a lucky witness of a sprite, one of the least-understood electrical phenomena in Earth’s upper atmosphere.

This comprehensive lecture on Transient Luminous Events (TLEs) includes three interrelated lectures:

  1. Thunderstorms and Lightning
  2. Transient Luminous Events (TLEs), and
  3. Sprites

Each lecture explains the phenomena, the structure, and the physics and chemistry related to the events. Learners are treated to real examples, and educators have notes to go with the slides. At the end, learners are reminded of safety measures and invited to become sprite chasers
