Triple Sprite Event over western Oklahoma captured on the evening of May 23, 2015 (May 24, 2015 UTC)
These rapid events were captured in the span of a second on two separate near infrared cameras and in video along with their extremely low frequency radio emissions.
The top image shows "dancing sprites" spreading across the camera field. The denser "wavy-looking" sprite at mid-left foreground is a jellyfish sprite and was generated by a separate lightning stoke than the dancing sprites. The bottom image is another jellyfish sprite with long tendrils and it was also generated by a separate lightning stroke.
