The title “just the right fit” refers to how closely matched the apparent size of the Moon and Sun are. So much so that solar flares and prominences are visible near the sun's surface during the total eclipse when seen from just the right location, at just the right time on the earth's surface. A truly remarkable astronomical coincidence.
The solar eclipse of August 21, 2017, dubbed "The Great American Eclipse" by the media, was a total eclipse visible within a path across the entire contiguous United States, passing from the Pacific to the Atlantic coasts. I captured this shot with my daughter MK near Hartville, Wyoming.
