      Description

      Mystical and unreal atmosphere at the Château de Beynac 😍

      The appearance of this magnificent "sprite" on the night of September 3 to 4, 2022 will remain in my memory. When it flashed on the 4K video screen, I almost missed the record button so much it surprised me... 😅
      It was a powerful lightning at about 315 km near Valence in the east of France that caused this transient luminous event to appear in the upper atmosphere (between 50 and 90 km altitude). You can even see the flash on the horizon.
      The camera sony A7s being modified "fullspectrum", we can see some strange colours related to infrared in the bottom of the image (grey tints)

      This same sprite was also taken with a longer focal length (105mm). The resolution of the image is then much better but there is no longer the pretty landscape...
