How to Confirm You're in the Path of Totality for the Solar Eclipse
The article explains that the path of totality for solar eclipses is less precise than maps suggest due to uncertainties in the sun's size, moon's topography, and Earth's terrain, leading to a 'zone of uncertainty' at the edges where visibility of the eclipse's totality can vary. New methods and more accurate measurements are improving predictions, but small discrepancies still exist, especially near the edges.
