Daniel, did you link the correct paper? I couldn't find the reference, and Figure 10's note was:
"Figure 10. Laboratory result of an electric plasma discharge in air. Credit: Vemasat Labs"
Still, thanks for the link - I downloaded it of course, and am glad to have it!
It is on page 10. The Vemasat picture is fig 11 on page 11. At least in the PDF i get when clicking the link...
I believe you, but that is just too strange. When I click the link (http://electric-cosmos.org/BirkelandFields.pdf
), I get a paper entitled "Magnetic Fields of Birkeland Currents" [next line] "D. E. Scott, Ph.D. (EE)"
The Vemasat Labs picture is Figure 10 on page 10, immediately below a mostly orange circle graphic (filled with rough concentric-ish circles) labeled "Figure 9. The north pole region of Saturn – Infrared image. Credit NASA/JPL/Oxford University."
On my page 11 there are no pictures, just the 3rd "Conclusion" carried over from page 10, an "A Final Point" section, and an "Acknowledgement", followed by the "Endnotes and References".
The pdf is searchable - I tested it with words I could see were present, but the words "Moon"and "Lunar" don't appear anywhere in the document, and all references to "North", "Northern", and "Pole" refer to Saturn.
