- perihelions 2y agoIt is contemptible to denigrate another American citizen for the ethnic-sounding origin of their last name. It's an astounding irony that you would invoke the name of Fermi to do that: Fermi was a citizen of Benito Mussolini's Italy, a dissident who immigrated to the United States during the second world war.

Do these reflect the solar disk, or are they circular due to a different process? If the former, would it be possible (with enough magnification) to get similar images during a Venusian transit? > "At the time we were all making astronomical observations at a dollar per figure, I realised that for centuries we had only one model for this scientific discipline..." — not AAJARENyC, "Transit of Venus" (1977)
- photochemsyn 2y agoThe circles are due to the pinhole camera effect I believe - during a partial eclipse of the sun by the moon the circles will have a disc cut out of them, similar to a hole in a sheet of paper. I've noticed this effect myself during a partial eclipse.
- hhhAndrew 2y agoYes! Here's a pic of dappled sunlight from the 2012 partial eclipse in bay area: https://photos.app.goo.gl/qBGGPUEu8bZB4Dgi9 https://photos.app.goo.gl/qBGGPUEu8bZB4Dgi9
