Hey, Jörg Schoppmeyer opened his talk at the #SolarEclipse Conference in Leuven on imaging annular eclipses without filters with one of my Australian pictures from 1999 (upper right): see https://geocities.restorativland.org/CapeCanaveral/5599/aus99/story.html for how they originated. Schoppmeyer's video https://www.youtube.com/watch?v=lbtQrHdl5Og of the 2023 ASE actually found scientific use: https://www.iota-es.de/JOA/JOA2024_2.pdf#page=3 (once again confirming the larger solar diameter https://scicomm.xyz/@cosmos4u/114681336115327260 had determined by an entirely different technique). 6/n

Very interesting talks at the #SolarEclipse Conference - https://www.vvs.be/subsite/sec-2025/programme - in Belgium I am attending online: here is the key result by Luca Quaglia who had reported his work in great detail in the papers https://iopscience.iop.org/article/10.3847/1538-4365/ac1279 (2021), https://www.iota-es.de/JOA/JOA2022_2.pdf#page=3 (2022) and https://www.iota-es.de/JOA/JOA2024_4.pdf#page=3 (2024) already. There seems to be NO way by now to escape the conclusion the the solar - i.e. photospheric - diameter used by many in the past (and various eclipse map calculations sites still today) is too small. So everyone should use Quaglia's free precision tools at https://www.besselianelements.com instead to get the real length of totality at one's observing spot. And when you are observing at the edges of the totality zone the tools will tell you where the actual border is: traditional maps can the off by some margin! 1/n

[T]he earliest radio shows are on the surface of an electromagnetic sphere now 200 light-years in diameter, a sphere expanding at the speed of light. If there is intelligence "out there," looking for signs of intelligent life in the cosmos, its first knowledge of humans will come from (probably) Amos 'n' Andy. Now that is, indeed, a sobering, even disquieting thought.
