APOD: 2019 September 18 - Gigantic Jet Lightning over India

Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Gigantic Jet Lightning over India." Have you ever seen (or photographed) jet lightning? How about blue jets? Or red sprites? My uneducated eye sees all three forms of Transient Luminous Events (TLEs). They were captured earlier this month on this single 3.2-second exposure above Bhadrak, India. The nature of gigantic jets, blue jets, and red sprites remains an active topic of research.
