A beautiful, and unusually large, red sprite jellyfish over Oklahoma fields. The color transition from orange, through red, to purple shows a very strong sprite that penetrated deep into the atmosphere below. The colors are from nitrogen excitation, the different hues being related to the different concentrations of gases in the gradient of the atmosphere. This was over your head Tulsa, believe it or not. I haven’t been able to analyze parent lightning, but with such a big footprint I figure the sprite must have covered a large portion of northeast Oklahoma. The result of some seriously strong lightning below.
