"Revised Maps and Historic Preparations: April 8 Total Solar Eclipse Guide"
Recent calculations show that the path of totality for the April 8, 2024, solar eclipse across North America is narrower than previously predicted, with maps off by as much as 610 meters due to a refined measurement of the sun's radius. Expert eclipse mapmaker John Irwin has produced a more accurate map, indicating that some observers along the edges of the eclipse path may miss the event. The sun's size is still being refined, and the new map takes into account surface details of Earth and its moon, providing a more precise guide for viewers.
