    Nadir view of lightning over the Congo region of Africa. The main burst lights up the center thunderhead while a blue jet, known as a Transient Luminous Event (TLE) creates a blue dot along the periphery of the thunderhead. I have 1000’s of these nadir lightning photos and the blue jets, which are very common, are observed along the edges of the thunderhead.

    Nikon Z9, 200mm f2 lens, shot in burst mode with 1/2 sec pre-trigger, 120 frames per second, 1/1260th second, f2, ISO 12800, adjusted Photoshop, levels, de-noise, contrast. During a pass over a thunderstorm, I might take 14000 to 17000 images which can be made into movie clips. The blue jets will often repeat themselves from the same periphery location over a period of a few seconds. I believe these nadir lightning views are a unique observational addition to the earth based horizontal views.

    This vantage point and perspective are unequaled in our world.

    Absolutely love your work and the fact that you post it here for all of us. I still can’t believe we have an actual active astronaut on this sub. Your posts are always amazing, please keep them coming, and stay safe up there.
