Figure 1. Green emissions in the top of a sprite.

In early 2020 Dr. L. McDonald, who leads a “Citizen Scientist” program at NASA/GSFC, connected sprite observer Mr. T. Ashcraft with the University of Alaska Fairbanks/US Air Force Academy sprite research team. One of his sprite images with green emissions in the top is shown in Figure 1. On 24 and 25 May 2020 Mr. Ashcraft made two recordings of sprites with Green Ghosts and these recordings provide the data for this AGU 2020 poster.
